Incus disk device

I had a setup with ubuntu 22.04 and lxd, and I am trying to convert this into debian 12 and incus.
All my containers have a common read-only disk device with some shell scripts.
On the host all scripts have root as the owner, but in the containers the owner is nobody, so some scripts don’t have enough permissions.
Can I change something so that in the containers the owner is also root?

Try setting shift=true on the disk device that’s added to the instance.

Indeed, owner is now root.
Thanks for your quick response.
