source          | session

Something is setting the value for the session.

Have you used

https://www.postgresql.org/docs/current/sql-alterrole.html

or

https://www.postgresql.org/docs/current/sql-alterdatabase.html

to SET tcp_keepalives_idle?

Doing:

select * from pg_db_role_setting ;

will help answer the above.
