Update config for all the tenants at a time at runtime

[KrishnaJyothika]

How to update any specific config parameter for all the tenants at a time at runtime.
For example I need to update max_total_query_length to 12h for tenant-a and max_total_query_length to 24h for rest of all the tenants. How can I setup this in runtime config?

I have tried using "*" but it is not working. It is working for the specific tenant not for all the tenants.

overrides:
'*':
compactor_blocks_retention_period: 10d
ingestion_rate: 0
max_global_series_per_user: 300
max_total_query_length: 24h
"tenant-a":
compactor_blocks_retention_period: 60d
ingestion_rate: 0
max_global_series_per_user: 10000
max_total_query_length: 12h
