my first post here, cheers to all fo you

I am wondering if for this model there is any way to update the bios... asking because I would really like to boot from USB to install Unix distro in parallel with Win11.
So far I managed by taking out the SDD, install using another PC, and that's OK but... way annoying.
Do you kow if there is some site / source of info to upgrade the bios?
Thanks!
