tubeless specific tires have different sidewalls (stiffer) than non tubleless and end up being heavier (you can see the weight difference in the spec (gp5000 about 50 gram difference)
as in all things bike and in life you may be able to make do, but you will better results using products/models designed for what you want to do
this falls in the pennywise, pound foolish area
and OP will find that trying to dictate the discussion is futile
