Most of the log above seem to be referring to S3 which is AWS command line utils. You will need to use google CLI which minimally require python 3.8.

How can i do this ?! because i'm working on VM directly via Google Cloud console.

You will need to provide details of what your snakefile looks like for others to help. Please verify that the SRA accessions you are downloading allow free egress (not all do) otherwise you will need to pay for the downloads.
