Is there a way to wire a battery into this circuit?

If you have it in the stock 1590A enclosure, you can use one of these to connect a 9V battery to the external power jack:  https://www.amazon.com/Mr-Power-Battery-Converter-Connector-cable/dp/B07FCZZ5JF

With a larger enclosure that has room, you can add an internal 9V battery clip.  See https://www.madbeanpedals.com/tutorials/downloads/StandardWiring_MBP.pdf
