Alternatives to support interface for PET, PAHT or PA6GF

The discontinued product is on the website. What alternative do we have to be able to use support interface?

Thanks

I use ABS as support material for nylon. I haven’t tried any support material for PC yet, as it wasn’t necessary, and I haven’t printed with PE yet. However, I would try it with PLA, as it works well with PETG, which is very similar.
