USB HS is disabled in CubeMX when LTDS is enabled on H743VIT6

I'd like to use both of the Synopsis USB controllers on the STM32H743VIT6, one as device, one as host, but to do that I understand that the other USB controller is accessed through the USB HS device, which is disabled because of the use of LTDC.

Currently I have the FS USB device working as switchable dual-role Host/Device.

I don't know why the HS USB controller is disabled by CubeMX, as the pin outs for HS DM+/- are free.

Is there a way to get around this to use both USB controllers and the LTDC?
