OpenSUSE Leap 15.3 with Mellanox ConnectX6 DX(inbox driver) support NFSoRDMA?

Hi , Experts

I have OpenSUSE Leap 15.3 installed on our server clusters.
Mellanox Connect-X6 with inbox driver is installed under auto-detected ( Since offical OFED driver not compatible with OpenSUSE Leap 15.3 system)
I heard from Mellanox customer support OpenSUSE Leap 15.3 with OFED community driver does not support NFSoRDMA .
Could you confirm OpenSUSE Leap 15.3 + Mellanox Connect-X6 (inbox Driver) support data transfer under NFSoRMDA?
many thanks!!
