Here's the response from Best Malz when I asked them whether I need a protein rest or not for their Pils malt.
actually there it is no problem to skip the protein rest, the malt is modified enough. If there should be some problems anyway or if you brew a stronger beer, I would recommend to mash in at lower temperatures (38° Celsius) and rise temperature directly to the first rest (64°Celsius). This time of rising up should be enough to solve some more proteins and also to reduce the ß- Glucans.
I hope this will support you,
