Mediatek Wifi and 6GHz bands?

So, got my Wifi 7 router in today. Good news, all the 6E and 7 cards from Intel and Qualcomm work without issues.
Bad news…all the Mediatek (6E and 7) don’t see the 6GHz channels. They show they support it, but it shows up as disabled. This happens to be on a 7922A (6E) card on Endeavour, but it’s the same on the 7925 (7) card (also on Endeavour).

        (5490 - 5730 @ 160), (6, 20), (0 ms), DFS, PASSIVE-SCAN
        (5735 - 5835 @ 80), (6, 20), (N/A), PASSIVE-SCAN
        (57240 - 63720 @ 2160), (N/A, 0), (N/A)

So obviously shows 2.4GHz and 5GHz compatibility working.

So all 6GHz channels are disabled.

Anyone know how to get them to be enabled?

As a rarity, I found the answer!!!

You need to install the wireless-regdb and edit the /etc/conf.d/wireless-regdom file to set your region. THEN it’s available!!! Happened to go down a rabbit hole and found the instructions for Framework AMD edition that explained it (uses AMD RZ616, which is just a restickered MT7922a).

So now just need to figure out how to do this on Debian.
