How to avoid using XA data source, when both the business-db and bonita-db in same host?

I'm using Bonita 7.6.1 with Mysql 5.7.

How to avoid usage of XA data source/connector when both Bonita and business databases in the same host. I've seen the non-XA datasources defined somewhere in the configuration, but I couldn't find where to specify it, so that Bonita will use the non-XA data sources.
