Another disclaimer: I don't use gparted (unless it's built into the
installer, in which case I have unwittingly used it) but fdisk and
gdisk as appropriate.
When you run those programs, they don't AFAICT claim ownership of the
device. You can happily run two instances of them without any problem,
though I haven't tested what happens with the second if you change the
partition table with the first (and the kernel rescans it).
Are you expecting a lock file to be created by fdisk and gdisk?
Even if you could "protect" the device with the partitioning
program, as soon as you exit it, there's a race condition between
your fingers/mouseclicks and the automounter, which the latter is
likely to win.
So my advice remains disable/uninstall the automounter and check
your DE options.
YAD (yet another disclaimer):
In looking through automounting issues on this list, I happened upon
https://lists.debian.org/debian-user/2016/11/msg00857.html
Regardless of the topic in (1), paragraphs (2) and (3) might make
a good signature for some of my posts.

And my anecdote (also OT):
Having done the steps in (bump, bump)
https://lists.debian.org/debian-user/2018/02/msg00466.html
(which might be too uncommon (mixing FAT and LUKS) or too technical
for this list), one instance of Windows10 (and only one) keeps
pestering with this drive about wanting to format F: (E: is the NTFS
filesystem). The only way to stop it is not to answer; just leave the
dialog box hidden underneath the normal windows. Dangerous, I know,
as one might accidentally click it after closing all the other windows.
But it made me think about whether you could stop the automounter by
setting a peculiar partition type on the device. Probably not; ho hum…
Cheers,
David.
