Hi, no, sorry – if you can’t do it with CSS you’ll need to modify the code. There might be some workarounds, for example you could remove the value using javascript or jQuery, or perhaps create a translation file that maps it to ” – but it’s probably easier to modify the code and just delete the value.
The next release includes templates you can modify and save so hopefully you’ll have at most one more update to change. I don’t have an ETA for it yet.
