Non-spiritual AA alternatives

I’m currently involved in AA, have a sponsor and just started working the 12 steps. Something about this program rubs me the wrong way though and I don’t like how much pressure my sponsor is putting on me to do things like read the big book and go to meetings- like leave me alone lmao. I’d rather do a program that is self-reliant and more at your own pace. Not to mention I’m agnostic and AA is “spiritual” but basically religious with how much god is mentioned. Anyway, any secular suggestions of programs I could get involved in instead?
