Unfortunately your motherboard doesn't have the option to flash the BIOS without power it up nor is there an option to recover the BIOS in case the BIOS update process goes sideways. In the event of the latter, you will need to use a CH341A BIOS Programming tool kit to revive the BIOS on the board.
My bios version is 2.A0.
FYI,
https://www.msi.com/Motherboard/Z490-A-PRO/support#bios
the BIOS version you're stating is not listed on the site, which would mean it was pulled off the site due to instability issues or worse, it ruined functional systems.
Do you think I can use an 11th gen cpu with my current bios?

Nothing with an entry for 11th Gen has
2.A0 listed next to it. So the answer from me would be, no.
