This issue persists for quite some time, the mt76 driver does not
call mt76_eeprom_override upon initialization. I'm sadly not aware why
this is the case. A PR for this is open in mt76 for quite some time.

You might have some luck pinging mbd directly or going thru linux-wireless.

See https://github.com/openwrt/mt76/pull/209

Best wishes
David
