/var/tmp is defined as a persistent tmp, and changing this to tmpfs might break
other software that depends on /var/tmp being persistent.
And changing them on a running system is not recommended since other software
might be using the tmp.
The best approach is to use state: present and reboot.

Default they are pointing to ~/.ansible/tmp

A grep in the source it seams that some module and plugins have /tmp hard coded
and maybe the code you are running is creating files in tmp.

Sort of, use present and reboot.
