You need to remove the action that WC added by doing something like
remove_action( 'admin_print_scripts', array( $this, 'disable_autosave' ) );
There are two tricky parts to doing that well
- This needs to run after WC add its own action
- you need to figure out how to find the exact same
$this
value that was used when the action was added.
I would still advice to get in touch with WC support because only they might guaranty that disable_autosave
is a stable function name that they are unlikely to change in the next version
