Is there a command line argument for reading from the DDC but not writing to it?

I want my cooking to benefit from the DDC but not contribute potentially bad data to it.

what is DDC though?

Derived Data Cache

i don’t have enough knowledge in this, i can only give a few possible clues. if that’s a file, you can always create a temp copy of that and “unsafely” read from it. alternatively linux “cat” command should output the raw data from the file.

not sure how helpful is that.
