It's possible to run into the default timeout of 5 seconds with quite
a simple and generic Debian 12, kernel 6.1 test VM. Detaching happened
right after doing a lot of IO on the associated drive.
In testing, detaching the drive itself was immediate, and detaching
the VirtIO SCSI controller always took 6 seconds. Use 15 seconds, so
that it's more than twice the value to be on the safe side for the
future.
For completeness, the VM configuration:
