AMD was developing an ARM core "K12" in parallel with the Zen core. K12 was delayed in order to prioritize Zen, Zen turned out to be a massive hit, so K12 got delayed indefinitely.

Once Apple released M1, rumors of AMD ARM development started again https://www.techspot.com/news/87851-amd-rumored-working-arm-...
I have a vague tickle in my memory that both Intel and AMD have dabbled in ARM before.
Even if they don't assign large production volumes to it now, they could still have a design team working on it for a contingency plan.
