Hello aspirant,
Yes, you can participate in MHT CET counselling for admission into government engineering colleges in Maharashtra based solely on your JEE Main score. MHT CET counselling considers both MHT CET and JEE Main scores for seat allotment, but appearing for MHT CET is not mandatory.

I hope this information helps.
