VDI Machines with Tesla T4 wont provision in a Horizon View 7.7 Instant Clone Pool

UNKNOWN_FAULT_FATAL - No GPU Capable host available for provisioning hostname with profile grid_t4_1q.

Two platforms. Dell R740 and HPM510 both with Nvidia T4 cards in. Same issue with both vSphere 6.5U2d and vSphere 6.7U1. All cards have ECC Disabled and are in Shared Direct. Driver in use is 7.1. Will try with 7.2 next week. nvidia-smi shows no issues. Windows 10 1803 in the SOE.

Solution is the graphics properties listed in the VMware KB which I couldn’t find previously!
