Firmware update after erasing disk in Disk Utility?

So I'm trying to update my old MacBook Pro (mid 2014), which still had Yosemite on it. As I ran into problems patching it to High Sierra first, I tried to install Big Sur after a recommendation in this sub. Creating the installer went well, and after rebooting I erased my disk to get a fresh start. Only problem:

When trying to choose this volume to install Big Sur, it now says that the Mac needs a firmware update to do so, and that I instead use a Volume in "Mac OS Extended (Journaled)" instead.

Can I just change the formatting of the main volume to this and continue? Or is there another solution?
