Yes. You need VBIOS, MB BIOS and Driver.

I'm pretty sure one of the primary things needed is for the motherboard & processor to support it, along with drivers.
 
If a BIOS update is necessary, eVGA will likely pump it out through Precision X1.  But the primary thing that needs to happen is for NVidia to enable it through drivers, and them working with both AMD & Intel to make it compatible & work with both types of processors on the modern chipsets.

It's not going to work on anything older than Z490 on Intel from what I understand currently, and same can be said for it not working on anything older than the previous gen of AMD as well - but that could change.

Can the vbios get updated through precision x1?

No. EVGA will post Bios updates, and users need to use the bios update file that EVGA posts.

Precision does not update the bios.

Actually my Aorus Z390 Master MB just had a Bios Update that supports Resizable BAR.

Interesting.  I'll have to do that & see what happens, gotta make sure I have all my BIOS settings memorized first though, don't want to lose the memory tuning I've done to a BIOS update. lol

I had to download a bios update for my 3090 strix oc today that was specifically adding support for the resizable bar to the gpu. Also bios update to my asus motherboard was issued for resizable bar as well.

I also own an Asus 3090 Strix OC. Where can I get the updated bios from? I don't see it on the official Asus support page for said card. Please advise? 

I get so triggered when I see people say they updated their bios with Precision X1. PX1 does NOT and can NOT update your vBios. It updates FIRMWARE for the LEDs on the cooler...that's all it does. It does not update your vBios and it cannot do this.

I assume you're talking about an earlier post somewhere and not mine, I never mentioned px1 anywhere.

There are many posts of people saying Precision updated their bios because they see the word Firmware and think that means bios. Spraying isn’t directing it as you, from what I can tell, but there are plenty of people that are quoting things that they don’t understand.

Now that we have the BIOS (at least EVGA and ASUS Mobos, not sure about others) I guess we will just have to wait for Nvidia to release the drivers and EVGA to release the vBIOSes

I like to take pictures of my BIOS settings. It's easier than trying to memorize everything.

Thankfully this is the case. I have no plans on installing Precision X

same here, Aorus released a BIOS update for my Z390 Ultra, to support BAR.  Cool!!  I've installed just fine.  Just awaiting the new driver now...

Great news! Asus will most likely have a ready bios update for our 3090 Strix OC next month which will implement the resizable BAR feature and address some other issues. Has for my X299 MSI Motherboard. There's already a beta bios release out. NVIDA will play catch up within the next couple of driver revisions. It's all thrilling free features.
