SUMMARY

Issue: Unable to adjust delay or dwell time for "Disable while typing" on my track-pad, resulting in unintended clicks, particularly while typing.

STEPS TO REPRODUCE
1.  Enable "Disable while typing"
2.  Make contact with track-pad while typing.

OBSERVED RESULT
Click is registered moving the cursor regardless of whether the user is typing or not.

EXPECTED RESULT
While user is typing (or within a customizable range) the track-pad is disabled and will not register input.

SOFTWARE/OS VERSIONS
OS: Fedora 42

ADDITIONAL INFORMATION
This is the most up to date (stable) version of Fedora to my knowledge. I apologize if this has been addressed.

This feature comes from Libinput; we just expose the option to turn it on or off, and can't offer configurability for it until and unless Libinput adds that too. So you'll need to request that over at https://gitlab.freedesktop.org/libinput/libinput/-/issues/.

Personally I'd recommend just disabling the feature, and allowing Libinput's built-in palm rejection feature prevent accidental touchpad movements. It works 100% of the time in my experience across 6 models of laptop over the past 8 years.
