My black tank flush anti siphon valve was located between the shower wall and the back wall of my entry closet. There was an access panel there, but located in the wrong area. But I could reach in and feel the valve and know where to cut a new hole. I cut a new hole there, saved the piece I cut out, and used some trim wood to make a picture frame for it, and used 4 small black screws to attach it. Looks better than the plastic frame on the original cutout.
Note that I eliminated the anti siphon valve and now use an external check valve at the outside flush connection. Those anti siphon valves have a history of leaking.
