I am placing the AMDev board inside a 2 inch waterproof enclosure and the input jack is too close to the side and cannot insert the TRS jack (see photos). How can I connect signal inputs to the board and bypass the physical jack?

Another option is to use a standard AudioMoth and de-solder the battery holder. Then the 3.5mm socket is on the short side.
Any soldering iron intended for electronics will work for soldering to the upper surface of the existing solder tags. The reflow section is really about the temperature profile when the whole device goes through an oven.
The AudioMoth Dev 1.0.1 uses a CUI Devices SJ2-35894D-SMT-TR socket:

It is different to the socket on the 1.0.0 versions of both boards as the original is no longer manufactured. To bypass the actual socket you can make connections directly to the solder pads as below. The 'Signal' is normally connected to the tip of the 3.5mm plug, and the 'GND' is connected to the sleeve. The 'Jack Detect' should be connected directly to GND to tell the AudioMoth Dev that a plug has been inserted into the socket. If you disconnect the 'Jack Detect' wire the AudioMoth will use the internal microphone and ignore the signal from the 3.5mm socket.
