How to remount a drive without root?

I want to allow a user script to remount a drive as "ro" or "rw".

By using the user option in the fstab, I can successfully mount and unmount the drive as a user but the -o remount,rw fails.

Is it not possible for the user to use the remount option?!?

/etc/fstab reads...

UUID=789f-4b3a-b0b2-c05955d7c5ad /mnt/nasbackup auto rw,user,noexec 0 2

but...
