IIRC systemd can do this for you but probably only if you are mounting the drives from /etc/fstab. If you're using the desktop's automounter, A. you should really switch to using /etc/fstab (Samba starts before the desktop and things won't get mounted if a user never logs in), and B. it may be possible but I have no idea how.
Your requirement to "automatically putting the device in the folder I am sharing back into read-only mode" seems an odd one and implies that the mountpoint will be writeable over Samba when the partition is not mounted. Easiest way to make something read only for clients is to set that in the share definition. Other methods include setting permissions on the empty mount point and the mounted partition's contents; and mounting the partition read only.
The mount options you need to investigate are x-systemd.automount and x-systemd.idle-timeout=T where T is the time in seconds after which an idel device is unmounted.
