I can not seem to find a clear ruling regarding the 'partner with' mechanic. So, the 2 commanders are in your command zone. When you cast one of the commanders, are you allowed to take the other commander into your hand? Or does it stay in the command zone? Also, are you allowed to put 1 of the commanders in your main deck and the other in the command zone? ( I assume you can not, but just checking)
The "partner with ~" is an ability that represents two different abilities.
The first only applies to the commander format during deck building. Cards that partner with one another may be your commander together.
The second ability is spelled out in the reminder text. When the creature enters the battlefield target player search their library for the partner card.
If they are in your command zone searching your library won't help. You don't get to put them from your command zone into your hand that isnt what the ability does.
If you choose to only run one as a commander you won't be able to have the other in your deck due to color identity restrictions.
However if you are simply running both in your commander deck when you play one you can search for the other.
You cannot add the other to your hand. The partner with ability only allows you to search a library for the named creature and no other zone so it will stay in the command zone. And no you cannot put one in your deck they both start the game in the command zone.

It stays in the command zone. The ability allows you to search only your library for the other partner. Your command zone isn't your library.
Also, are you allowed to put 1 of the commanders in your main deck and the other in the command zone?
If you have both as your commanders, they must begin the game in your command zone.
If you have only one of the partners as your commander, then the other partner doesn't fit the Color Identity of your deck, and therefore it can't be part of the deck (this is true for all the Partner With pairs printed so far).
Now, IF one of the Partners is somehow put on the library, and you choose to let it go there (rather than putting it back on the command zone instead), then you can use the other Partner to get it to your hand.

It makes more sense when you realize Partner With isn't a new ability for Commander 2020. It was originally designed for Battlebond (see: Pir, Imaginative Rascal/Toothy, Imaginary Friend), a set focused on the Two-Headed Giant format. There are even some non-legendary creatures with the ability, such as Chakram Slinger/Chakram Retriever. The intention for the "search your library and put it on your hand" effect was that you would draw one from your deck, play it, and then you or your teammate gets to search for the other card.
The "you can have two commanders" bit was just an additional effect they decided to include, even if it kinda negates the main "search for my partner" main effect. Because otherwise you'd have two potential Commanders with synergy that just couldn't be played together.
"Partner with" allows the targeted player to put the other card from their library into their hand. The command zone is not the library. If you target yourself and no card with the other name is in your library, the "partner with" will do nothing for you.
You sure can designate just one of the cards as your commander. "Partner" does not force you to also have the other card as your commander. The other card will then not be a commander, though, obviously, and you probably won't be able to include it anyway due to color identity issues.
