Is it true that cruise lines are not allowed to sell alcohol and certain foods whilst in Israeli waters?

All being well regards to the current epidemic I shall be embarking on a cruise this November 24th which includes a two day stop in Israel. Obviously as a middle aged male the all inclusive drinks package will be one of the highlights of the cruise over that of the free water flumes. However, I have been informed by an unofficial source that whilst in Israeli waters the cruise line will not be allowed to sell alcohol, and certain foods will also be banned until back out of Israeli waters. This could mean two or three days without alcohol which makes an all inclusive drinks package less beneficial, so thus I may pass up on the all inclusive drinks package and simply pay as I go, unless of course it is not true that they will be required to stop serving alcohol.

So do cruise lines traveling to Israel need to stop serving alcohol whilst in Israeli waters?
