Yes those bios settings are required, plus a few others.

Disable​

• Fast Boot
• Secure Boot

• VT-d (can be enabled if you set DisableIoMapper to YES)

I will install Windows 11 on another partition if I would like to play, and based on your advice, I looked at these two cards: Asus Dual Radeon RX 6650 XT O8G or ASUS ROG STRIX Radeon RX 6650 XT O8G GAMING

Either RX 6650 XT card should work just fine in Monterey 12.2.1+ or Ventura, with the appropriate boot argument - agdpmod=pikera added to your config.plist.

You may need to add the device-id for an RX 6600 and a few other entries to the DeviceProperties section of your config.plist too.

They would look like this.
