23 Tacoma ABS issue

Hey everyone, I purchased a new 23 Tacoma off rd last year and put on a 3” rough country lift with 285/70r17 Goodyear duratracs. l did this when it had 9,000 miles. It now has 20,000 and I am currently having an issue where my brakes will lock up driving on back roads. It has now happened 3 times and can’t seem to get a definitive answer from anyone. I was told alignment, but drives fine. Was also told the slight change in tire size but my dealer won’t reprogram because of using an off brand lift. Any insight or expertise would be appreciated.
