Hi @larrys69004
Here's the https://download.lenovo.com/consumer/mobiles_pub/legion_5_15_17_6_hmm.pdf|hardware maintenance manual] that may help.
On p.31 there's a list of the tools required and on p.63 → p.64 it shows how to remove the thermal module, if this is the part you mean.
It doesn't mention anything about unscrewing it in any particular manner or even which size screwdriver to use
