Prevent prefill fields

Hi, we have a shop where only logged in users can order.
We have an extra checkout field where buyers can enter a ‘commission name’, sort of referral.

But in the next orders, that ‘commission name’ is already filled in. Same as the names.
But for the commission field, that is something that we don’t want. No autofill.
But i guess this is a browser thing, as i also have read in previous support tickets.

But there is a solution out there like autocomplete=”false” for input fields, that prevents those issues.
Is something like that possible in your plugin (or pro version).

Or is there another way to prevent autofill?
