Can you put “minwax wipe on poly” over “Boos EZ-DO gel poly”

I applied 5 coats of EZ-DO to a kitchen island, allowed 24 hours between each coat, and the island cured for 5 weeks before it saw any use. The second water hit it, it left water marks. I am wondering if I can do a light sand and add the wipe on poly to get a more durable finish without sanding down to bare wood and starting over.

I've never used it, but it sounds horrible. And their marketing is filled with nonsense, like being "food safe."
If you sand to bare wood, you can use any finish. If you want to sand lightly, put a coat of defaced shellac, then good quality poly on top.
Unless you are throughly experienced with the finish schedule you are going to use... Always do a sample piece, same species, finish exactly as you intend to do the final piece. You will pay dearly at some point for failure to do this.
I think John meant de-waxed shellac. This will act as a barrier coat and "should" work but try it on a sample first. Zinssers Seal Coat is a good 2 lb cut de-waxed shellac. Check the label for the manufacturing date to make sure it is fresh. If you have no experience with shellac you should do a little research regarding brushes and techniques and practice a bit. It takes a different approach than slower drying finishes. You can also pad it on. https://www.finewoodworking.com/2014/10/01/seal-your-project-with-dewaxed-shellac

It looks like it's a combo of linseed oil, poly and oil resins with some mineral spirits. I'm not enough of an expert to give a definitive answer. Possibly you could put a wipe on poly successfully but the solution here is easy enough that I don't think it's worth chancing it....
As suggested above, get some dewaxed shellac to go over the current finish, THEN apply your wipe on poly. You may have to sand back the water marks. Try a test spot and see. Worst case scenario, strip it all back to bare wood and start over.
Larger lesson here... stick with finishes that are already proven and known. I'm always wary of any of niche type products. Unless you get reviews from real seasoned pros using them. The average customer review generally comments on basic looks without much real knowledge of the true ins and outs of what constitutes a good finish.
Thanks for the replies everyone. I ended up sanding to bare wood and started over, and the "EZ-Don't" sanded off way to easy. I'm still new to the finishing world (obviously) and would appreciate any more advise you have for me on the best finish for countertops. From what I have been reading Waterlox seems to be one of the best. Thoughts?
Waterlox is an excellent choice. It is easy to apply and provides a durable finish. Go to their site and read the technical data sheet and directions before you start. Also be careful with the saturated rags after application, if you leave them folded up they can generate enough heat curing to spontaneously combust and start a fire. I unfold and drape over a rack, trash bin or log outside so they can safely cure/dry, then discard.
It still would be wise to wipe on a wash coat of thinned Sealcoat as a barrier. Even though you have sanded it back, there could still be some residue of the previous finish that may cause problems.
