HA Supervised - Change /media to external drive

Dear community,

I have HA supervised running on a mini PC. I used to use a network volume to save frigate recordings (frigate being installed as an add-on).
I have seen multiple posts, but most of them are not related to the supervised installation.
I have seen posts with the ‘move data disk’ option, but it isn’t working on my system, for an unknown reason my mounted partition of 2Tb (/dev/sdb1) isn’t seen.
Any idea how could I achieve to move the /media to /dev/sdb1, rather than in /usr/share/hassio/media ?

Thanks!
