The file "my.gdb" is a simple text script file, which contains the lines(commands) below

Currently, I don't have an idea about whether "set auto-load" command is relevant or not. I use this script for several years.
I think for your original question, you need one line:

from libstdcxx.v6.printers import register_libstdcxx_printers

But you should let GDB know where the "libstdcxx" folder locates.

I just type the command below:
source d:/path/to/my.gdb
