cannot delete product instance

Hello Everyone,

Is there possible to delete product instance on TrendMicro Vision ONE? There are two types of product instance that we can create. One is Standard Endpoint Protection and another one is Server & Workload Protection. We had create both of them but we would like to delete Server & Workload Protection Instance because we will not install our TrendMicro Vision One agent on Servers. Any ways to delete product instance from portal or do we need to open a ticket to delete it?
