UCC21732QDWEVM-025: About using Transformer T1, T2

Part Number: UCC21732QDWEVM-025

UCC21732EVM

I understood as when VCC Power (5V) is given by external Power supply, VDD(15V) is made through transformer(T1, T2) internally.

But I want to put VDD (15V) Input Power externally using another Power Supply without using Transformer(T1, T2).

And this is the question, I wonder if it is okay to remove T1 and T2 and give input power VDD using external power supply?
