If there are no updates in the database, you can set it to READONLY, to
avoid the overhead of locking. But apart from that, there is no option to
do this on database level.

However, the application could issue SET TRANSACTION ISOLATION LEVEL
READ UNCOMMITED when it connects.

But I would definitely think twice before I took such a step. If you
have issues with blocking, maybe you should rather review indexing
than resorting to NOLOCK.
