Is it possible to programetically disable the creation of default emailable-report.html When a custom emailable report is getting created in testng

I have implemented a custom emailable report as custom-emailable-report.html with testng. Now in my test output directory I see there are 2 email reports getting generated. 1. Default emailable report (emailable-report.html) 2. Newly added custom emailable report (custom-emailable-report.html)

I want to have only the custom-emailable-report.html in the test output directory. So what is the process of programmatically disable the creation of default emailable report.
