By default we have Neoverse-N2 cpu which supports FEAT_RNG feature. Commit 5de5e230a80bed083360da95ba16a2c4a001620d (in EDK2) enabled that for ArmVirt platform.
RNDR is implemented by both Neoverse-N2 and 'max' cpu implemented by QEMU. Other cpu models lack it which prevents the RngDxe driver from running, resulting in the same situation as before. TRNG is not implemented in TCG mode but is required by RngDxe to run.
