A sealant that will seal the surface of the poly and then be protected by a thin nylon sleeve will work, if the hole is properly drilled and the lens is a poly produced without excessive internal stress. All poly lenses are not the same. There are products on the market to seal the drilled holes.
There are better materials for rimless than poly if you are not set up to properly drill and install the poly.
