I downloaded V3.9.7 and I'm facing the same issue.

I recognized that in the path /configure/esp32XX/multi_download.conf are the config files located. Especially the interesting section [ESPTOOL_PARAM]
after = no_reset
before = default_reset
compress = True
flash_size = keep
no_stub = False
verify ...

solution for those who cares: viewtopic.php?f=22&t=29065
