Yes.
The principle used in both the processes (i.e. IPO application via ASBA through bank or UPI process through broker + UPI app) is the same - as the abbreviation ASBA suggests (Application Supported by Blocked Amount) - the amount is only blocked but not debited and hence continues to garner interest as applicable, till the requisite amount is actually debited. This is the intention of introduction of ASBA by SEBI in 2008.
When one applies for IPO through a broker app (say Zerodha Kite), then the process is as per UPI Mandate and autopay through the UPI app (like Phone Pe, etc).
I have used this process i.e. UPI Mandate process through Zerodha Kite app for IPOs and I find it very easy and the whole process including UPI autopay mandate is completed in a few minutes with a few clicks. I have never used the ASBA process through my bank.

For difference in the two processes, see

Hope this helps.
