I've read that on https://docs.microsoft.com/en-us/sql/t-sql/queries/hints-transact-sql-table?view=sql-server-2017
Takes page locks either where individual locks are ordinarily taken on rows or keys, or where a single table lock is ordinarily taken. By default, uses the lock mode appropriate for the operation. When specified in transactions operating at the SNAPSHOT isolation level, page locks are not taken unless PAGLOCK is combined with other table hints that require locks, such as UPDLOCK and HOLDLOCK.
Does the option "Is Read Commited Snapshot On" is concerned by this or it is just the "Allow Snapshot Isolation"?
