I don't know if there is a how-to guide about adjusting the SPV wallet forked coin.

In any case, you can try to comprehend the ElectrumX protocol. Read their source code for both the server and the wallet, here are the protocol docs:https://electrumx-spesmilo.readthedocs.io/en/latest/protocol.html.

Also, it would be good if you try to see how Bitcoin Cash/SV and Litecoin implemented their own SPV. You can refer to their code about which part does they changed.
