Groin strain - squatting recs

Long story short - I strained my left groin about a month ago while back squatting and it's now become a recurring thing when I squat below parallel.

I typically squat on Monday and I haven't been squatting any other days of the week since this injury - just trying to get one decent squat workout per week right now. The groin feels fine during warm-ups (air squats, banded walks, hip rotation, etc.) but as soon as I start to put weight on the bar, I can feel it flare up again. I did box squats (slightly above parallel) yesterday and those actually felt fine. It seems to only flare up when I squat below parallel.

Here is my question: Would y'all just continue to sub back squat for box squat and stop doing lunges, belt squat, front squat, etc for the rest of the month? I'm currently doing a squat centric program, so I feel like I'd be losing a ton of leg volume by doing this. Are there any decent programs that you would switch to that have limited squatting prescribed? I know that PPSA does have some upper body focused programs - any recs on one of those that might have a low squat volume?

Anyone ever have a nagging groin strain and figured out a way to keep training or expediate healing the strain?

Thanks in advance!
