How to delete a parquet file from a existing context?

Background

I'm currently engaged in a project utilizing datafusion, which I find to be both convenient and efficient for database project development. However, I've encountered a confusing issue: once a Parquet file is registered to the SessionContext, it seems there's no supported method to deregister it. Consequently, if the file is deleted remotely, a NotFound Error is reported. Could anyone advise on how to deregister a Parquet file from a SessionContext?

maybe SessionContext 's deregister_table function can do this task. because register_parquet underly call register_table function.

The deregister_table function will detach the specified table from the schema; however, my intention is not to delete all the files contained within the table, but rather to selectively remove only certain ones.

The only way i know of to do this today is to drop the table and recreate it (which will re-scan all parquet files)
