Make s2idle resume faster?

My Yoga 7 2-in-1 16AKP10 only supports s2idle (not S3, no Bios option either).

Is there any way to make the resume faster?

It consumes barely any battery in standby (about 1% in 5h), which is great, but I would prefer a faster resume. Sometimes it’s resuming very fast, especially if it wasn’t in standby for a long time.
But most of the times the resume can take more than 10s.

I think the hardware goes to a “deeper, energy saving” suspend mode. I don’t need the low battery consumption in standby. Is there any way to change this behaviour?
