There are great interactive drawings for the more recent years and they let us "look through walls" and turn or zoom to get some really fine details of what we have.

HOWEVER? To get the correct group we have to know WHICH 2017 View?
If you can pick the correct RV, we can do a better job of looking at how your connections are built!
When choosing which RV, it may take looking down to the plumbing and fresh water section as there appears to have been three different builds in the 2017 year model for the 524G model. I did not look at others but one might assume there were changes there also, so that means there are differences in the fresh water plumbing. Getting the correct drawing at start will lead to better ideas of how to get it apart!
One common way working just from guess is that the port can be pulled forward after the two screws are removed. The two I looked at had the tubing behind the port going into an interior wall so access from the outside may be the better idea!
But that is guessing, so your choice on looking at the drawings or trying a guess??
