The three HWH bypass valves are right where they should be, behind the HWH. Unfortunately you need to be a contortionist with three double-jointed 40" arms to get to them.

Yes they have to be open because the blue hose was installed to eliminate the OEM water filter that was originally in that place.
Not only do they need to be open for winterization but they will need to be open for normal use too. The filter was originally plumbed into the main supply line for your entire rig so if you would close those valves, no water or antifreeze will flow throughout.
I'm not sure if those two valves were originally plumbed in for servicing the filter or not but now that the filter is removed, they should simply remain open all the time. There is no useful reason to close them now that the filter is gone.
