I don't think there is a way to force all applications to use a specific tmp file
directory location.
You can, however, change /tmp from being tmpfs to being on actual persistent disk storage.
Simply do,
systemctl mask tmp.mount
This takes effect on the next boot.
Also, many many programs (and all right thinking programs) will honour the
$TMPDIR environment variable. Of course you need to get that into the
environment of the running program. For stuff invoked from the command line
everything is easy; I routinely set $TMPDIR=$HOME/tmp in my profile. For things
invoked via desktop GUI buttony stuff, it depends on your desktop.
