Disable TOAST compression for all columns

I am running PostgreSQL on [compressed ZFS file system](https://bun.uptrace.dev/postgres/tuning-zfs-aws-ebs.html#disabling-toast-compression) . One tip mentioned is to disable PostgreSQL's inline TOAST compression because ZFS can compress data better. This can be done by setting column storage to EXTERNAL. I can do this column by column with:

ALTER TABLE my_table ALTER COLUMN my_column SET STORAGE EXTERNAL;

However, this might be a bit cumbersome, as every schema needs to have migrated to this by hand. Are there easy ways to - Set default STORAGE to EXTERNAL instead of MAIN for all columns - Disable TOAST compression other way I found [default_toast_compression option](https://www.postgresql.org/docs/current/runtime-config-client.html#GUC-DEFAULT-TOAST-COMPRESSION) but the documentation is unclear if I can disable it.
