Welcome to The Forum!

Is there water in the pool and the liner dropped? From your post, I assume so.

If moving the post is more trouble than using a hole saw to pop a new return inlet, move the return inlet.

There are some 'cautions' to drilling a new hole- you'll need to take the water down ~ 3" below the proposed site and keep any metal fillings from getting behind the liner!

It's not overly difficult, nor taxing on anyone who knows how to use an electric drill - however, it'd be best to run your plan by us, before you do it

I look forward to hearing back from you, so we can be sure that you don't, inadvertently harm your pool.
