Blacklist pipewire from zypper dup (TW)

Hi, As the subject says, I'd like to blacklist pipewire from dup updates in tumbleweed. Do not misunderstand me. I like pipewire and look forward to it becoming standard, when it's ready for prime time. Unfortunately, this is not the case at the moment and I rely on professionally audio with jackd etc. Anyway. What's the correct way to blacklist pipewire from zypper dup, and is it even possible without destroying the setup? PS. This might be more appropriate on the factory list but I start here.
