I would recommend to use an automounter to mount it automatically, if you need it
(i.e. on directory access) and unmount it after use. That is way better than trying
to workaround your issues.

You could use autofs (extra package) or systemd for that.

I believe https://help.ubuntu.com/community/Autofs is a good starting guide and
https://manpages.ubuntu.com/manpages/xenial/man5/systemd.mount.5.html (section
FSTAB) is a good reference for the systemd parts.
