Resizable Bar

I am having a hard time understanding if rebar is enabled or not on my bazzite install. I have an RTX 3070, in my bios i have enabled all rebar settings but going through arch wiki and other posts about how to check shows no information, for example
sudo dmesg | grep BAR=
Returns no results. I have tried a few other commands I found on reddit, but none of them are really showing anything. This leads me to believe that it is not on, but I am not sure why. thanks for any help.
Solution
I booted into windows and using MSI live Udpate tool (for my MSI gpu, different if you have other vendor) updated the VBIOS and it is now working.
