You can manage the index maintenance on the OS with Crontab if you want to make it concurrently.
If you only need index maintenance you can schedule it with pg_cron.
The only way to do this is to write a bash script in Linux and insert it with the loop. You can text the bash script for that.

Yes, read the documentation. CONCURRENTLY avoids blocking other
transactions, at the cost of being easily blocked itself.
