I highly doubt it. Plus him requesting a trade is like step 1 in a 10 step process that actually leads to him being traded.
Contract will almost certainly prevent it from happening.
if he really wanted to he could potentially force his way out in another year's time based on the structure of that contract but the compensation would have be right and the texans would have to be willing to deal which is exceedingly unlikely
but especially with the cap set to reduce and the texans already precarious position with regards to the cap it's almost completely unfeasible that it could happen in 2021
