Increasing /tmp beyond 10 GB

I need to increase the size of /tmp to 100 GB.
A new version of cPanel (136.0.25) includes the /tmp configuration within "Tweak Settings."
This setting prevents the /tmp partition from being increased beyond 10 GB.
In earlier versions of cPanel, this was handled in `/scripts/securetmp`.
Now, the option in `/scripts/securetmp` looks like this:
`my $tmpdsksize   = $use_custom_size ? $cpconf->{'securetmp_file_size'} * 1024 : $min_size;`
Does anyone know if it is safe—in this version of cPanel—to modify `/scripts/securetmp` as was done in previous versions by specifying the size, for example:
`my $tmpdsksize = 100000000`
(for 100 GB)?

  Hey there!  Yes - the details in the second half of this guide still work on a version 136 system:

  Is there a specific reason you need to create such a large /tmp area?

  Hi cPRex.
  Yes, I use Monsta FTP, with a large volume of uploads.
  When the `/temp` directory hits 100% capacity, the entire system freezes. Restarting Apache doesn't help; I have to reboot.
  I modified `my $tmpdsksize`, and it worked.
  Thanks!

  That makes sense, and I'm glad to hear it worked!
