CSI FUSE driver cannot mount DF 8.0 volume to pod on Ubuntu 24.04

[nightzone]

Ubuntu 24.04.4
Tried with different k3s and RKE versions:
K3s: v1.32.12+k3s1, v1.34.4+k3s1
RKE: v1.32.12+rke2r1
MapR CSI deployed from csi-maprkdf-v1.2.15.yaml
Create SC as per documentation.

ISSUE:
PV and PVC are crated as expected, but volume not mounted to pod.

Connectivity checked and is operational.
Same config on k8s v1.31.1-hpe1 on RHEL 8 is operational.
