Thank you for pushing this forward Lilian Kasem (@liliankasem)!

FYI, there is some additional context in the older issue #3112.

We're currently blocked on the python team releasing an arm64 build. They are planning for that to be in v4.x39 of the Functions Host - I don't have any clear dates on that but we are currently at the start of the process for v4.x38 so it may be a while. In the meantime we will prep anything we need on the Core Tools side so we're ready when that happens.
