If CSM bios setting is set to "disabled" PC won't boot...there is no picture, can't even enter BIOS.
GPU-Z says Sapphire rx570 ITX supports UEFI, and same GPU works with CSM disabled on another, AMD b450 chipset based motherboard.
BIOS is latest for H470m-hdv board, 1.30

Any ideas welcome, as I'd like to upgrade to windows 11

Windows must be installed in GPT (UEFI Mode)
Above 4G should be enabled, and Clever Access memory, also.
When you connect the onboard graphics, is the RX570 found in device manager.
If not check the pins in the CPU socket, or fill in the tech supprot form
