Podman rootless cannot mount NFS inside container

I'm trying to mount NFS inside Podman rootless container. I tried several method with/without CAPS and security profile parameters. Unfortunately, mount works only, if Podman is run as root. I'm spent 2 week on this issue, but honestly i'm out of ideas how to deal with this issue.

1. As root with cap-add container (Working)

[root@rack-host1~]# podman  run --cap-add=CAP_SYS_ADMIN -it myredhatimage:8 bash 
[root@d8e09797b797 /]# mount -vv -t nfs4 -o rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,local_lock=none,addr=10.0.0.12

nfs-server06:/MoviesShare /data mount: nfs-server06:/MoviesShare mounted on /data. [root@d8e09797b797 /]# ls /data configs containers movies logs pictures

2. As non root without caps [Failed]

[podman-user@rack-host1~]$ podman  run -it myredhatimage:8 bash [root@fbd0cfca851d /]# mkdir -p /data  [root@fbd0cfca851d /]# mount
-vv -t nfs4 -o rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,local_lock=none,addr=10.0.0.12

nfs-server06:/MoviesShare /data mount: /data: permission denied.

3. As non root with caps [Failed]

[podman-user@rack-host1~]$ podman  run --cap-add=CAP_SYS_ADMIN -it myredhatimage:8 bash
[root@56e79e6f30cf /]# mkdir -p /data
[root@56e79e6f30cf /]# mount -vv -t nfs4 -o rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,local_lock=none,addr=10.0.0.12

nfs-server06:/MoviesShare /data mount: /data: permission denied.

4. As non root with caps and privileged [Failed]

[podman-user@rack-host1~]$ podman  run --privileged --cap-add=CAP_SYS_ADMIN -it myredhatimage:8 bash
[root@bc40b4065cf1 /]# mkdir -p /data
[root@bc40b4065cf1 /]# mount -vv -t nfs4 -o rw,relatime,vers=4.0,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,local_lock=none,addr=10.0.0.12

nfs-server06:/MoviesShare /data mount: /data: permission denied.
