I'm in the same situation here. I have installed superset 4.1.2 in python virtual environment on redhat 8.8. My analytics database is Clickhouse and I want to enable Jinja templating for filtering based on logged in user and dynamic filtering on the dashboard. My understanding to enable Jinja templating in superset with Clickhouse is that I need to set Two things.

1. superset_config.py ENABLE_TEMPLATE_PROCESSING = True

2. clickhouse.py class ClickHouseEngineSpec(BaseEngineSpec):

supports_jinja = True

It is not working after setting these parameters and restart. Any guidance is much appreciated.
