Modifying the default ADR algorithm and adding your own ADR algorithm

Dear community, I have installed chirpstack server on my PC. I am aware that by default an ADR algorithm is provided. My question is if I want to modify the ADR algorithm, how to do that. Also, kindly let me know the steps I need to follow to use my own ADR algorithm in the network server. I went through several articles and got some hints but I need more information about it in detail.
