I am using a GT65thin i7 10 series laptop with the RTX 3060 built into it. It's not the same system as you have but I am experiencing the same problem. What I have done is open MSI afterburner and also Windows power management. Under MSI afterburner I have lowered the core clock and memory as low as I could take it. Ive played a few games and I've not seen a drastic fall off in performance so your milage may vary but it worked for me. Also, under windows power management, try going into the setting for processor power management. I lowered it down to 85% power consumption when on plug and 50% when on battery. I've played games like Destiny 2 and Halo Infinite and I haven't noticed too bad of a performance hit.
