PowerPlayTables not written

Hi !

For unknown reason OC does not work for 1 of my rigs:

=== GPU 0, 03:00.0 Radeon RX 5700 XT 8176 MB #1 === 06:48:10
/hive/sbin/amd-oc.navi.sh: line 88: /sys/class/drm/card1/device/pp_od_clk_voltage: Permission denied

/hive/sbin/amd-oc.navi.sh: line 84: /sys/class/drm/card1/device/pp_od_clk_voltage: Permission denied

Does anyone know how to fix this ?
