Need to update schema_option for an article that has subscription sync type 'replication support only' in SQL Server 2014

I am using SQL Server 2014.

In an already existing publication, I have an article that uses schema_option 0x0000000000000080. I need to change it as this doesn't allow custom procedure updates (I need to do DDL changes on the article at Publisher, and that is not being allowed).

Subscription for this article has sync type 'Replication Support Only'.

My questions are:

1. When I use sp_changearticle to update the schema_option, do I need to create a snapshot?

   Documentation says you must specify a value of 1 for the force_invalidate_snapshot parameter if you are updating schema_option.

   But since this is 'Replication Support Only', it should be fine if I keep force_invalidate_snapshot = 0?

2. Do I need to drop and re-add the subscription if I change schema_option using sp_changearticle?
