Got a very noob question but I was wondering since I have been floating most of my fast growing plants to maximize lighting and not have the plants overtake my tank if it was OK to trim off 80% of the roots that are growing down into the substrate. These plants are growing over 6" of roots. I'm talking about plants like lutweiga and camboba but not plants like amazon frogbit and RRF. I am just worried about if I cut most of the roots the plants would melt off or if it would just keep growing new roots.

If I'm not mistaken, those plants don't receive nutrients via their roots. The roots are there just to anchor the plant to something. I think you should be able to chop them off without having the stem plants die on you.
