I have a quest 2 with a ton of pirated games on it, you have two options, create a oculus dev account (no facebook necessary and sideload oculess (look up on github) now you have a quest 2 with no facebook. You can sideload paid games on it and enjoy. Unless you do a factory reset and login with facebook you won't be able to access app store or online standalone games. (pcvr and airlink work 100% like normal) 
Option #2 is make a facebook account. Use your real name. You do not need to be active at all. You can still pirate games and do whatever you want and you will be able to use it for online multiplayer app store etc. (Some pirated games even have multiplayer some don't) enjoy your headset.
option #3 is block facebook via your router with port options. This is a bad idea.
