I'm ~99% sure that ARM (and Apple Silicon Macs, by extension), are not yet supported. Went down many rabbit holes to attempt configuration of the Databricks ODBC driver and wasn't able to get it up and running. 

The evidence suggesting a lack of support:

1. The release notes of the Databricks Spark SQL drivers make no mention of it
2. Similarly, the release notes indicate a new version hasn't been released since 2022-07-12, which predates the first reply to OP.
3. In my Terminal, the command `file /Library/simba/spark/lib/libsparkodbc_sbu.dylib` shows compilation for `i386` and `x86_64`, but not `arm64e`.
4. During my rabbit hole exploration to set up ODBC, I stumbled across blogs like this one, indicating the issue still exists and requires a rather massive lift to solve for when using with R & RStudio.
