How to supply a different tmp directory?

[Kriskras99]

- name: Install paru using makepkg if it isn't installed already
  kewlfft.aur.aur:
    name: paru
    use: makepkg
    state: present
  become: true
  become_user: aur_builder

I'm trying to install paru, but the /tmp on my VPS is very small (only 460MB), so it fails with the following error:

error: failed to write /tmp/rustcLUEddL/lib.rmeta: No space left on device (os error 28)

error: could not compile `object` (lib) due to 1 previous error
==> ERROR: A failure occurred in build().
    Aborting...

Is there a way I can configure a different tmp directory?
