Hope all are doing well. Great forum and lovely people, helping each other

I am due to renew my Indian passport in the UK.
I am confused with PPF - Police verification form. Is it manditory to fill this form? if yes then what references I must give in the PPF form. I spoke to couple of my friends who renewed their Indian passport recently and they said they did not submit any PPF Form. But I spoke to the VFS Global customer service and they mentioned its manditory.
Can someone please share your experience, while renewing Indian passport in the UK, whether PPF - Police verification form is manditory or can be ignored
Thank You in Advance!
