How to control Input Color Space Rules automatically in Maya2022 without ocio config v2

I’m using aces config v1 , and opencolorio v2 . I’m trying to set Input Color Space Rules automatically so that I don’t need to do it manually through the settings/Preferences . Example I’m trying to make a rule for exrs file to always be set to Raw , and my v1 legacy config is overriding the ocio v2 config that Maya ships with , so the config is not providing the rules and v1 configs don’t support file_rules field

is there a way I can set the file rules automatically if not through the config ?

You can set file rules on the color management section of the Maya prefs.

You can also use aliases in an ociov1 config.
