Are all currently used EFIs require BIOS update?
Is there a way to update BIOS without installing windows?
Yes you can update without windows. You can just put the update.exe file onto a usb stick and start the update process through the bios.

All current EFIs require a few „Hacks“ in the bios. You need to disable the CFG Lock through a UEFI Shell.
If you want to install the newest version of Mac OS I would recommend:

My XPS runs BIOS 1.12.1 and Mojave with Clover
I remember I was able to run Catalina with Clover update with no issues, and even Big Sur, at least when it's already installed (had to plug ssd into MacBook to install it, back when it was just released)
At the moment, when I try to downloaded EFI with OC from this thread or GitHub or with Clover, both from Tonymac or GitHub, none of EFIs work with one error or another, which is sad and raises many questions.

I am still on BIOS 1.12.1 as well, so you should not need a BIOS update.
The biggest changes here when moving from Clover are BIOS setting mods, like removing the CFG lock, but this can be bypassed by enabling a quirk in OpenCore. If you are not familiar with how OpenCore works and the differences between it and Clover, I would recommend following the OpenCore guide, building an EFI from scratch, and installing on a fresh SSD just to get a feel for how it works and to familiarize yourself with the tools.
