Not sure if this is your app (I looked on Playstore but since I'm not from India, maybe I can't see all the regional apps):
Find vehicle Owner detail from their vehicle number. Check your driving license.

First I install and opened, it reported the root
I put to DenyList and rebooted - still reported the root
I added to my Hide My Apps, hiding Magisk app, LSPosed and modules, rebooted (and cleared Cache and Data for RTO app) and there was no more root detection popup - it asked me to select language and city (screenshots)
Maybe you don't even need HMA (eg, if you don't have LSPosed installed) but simply hiding Magisk app would work instead. You must test yourself
How to look for instructions on how to use DenyList, HMA, etc - you got info in the previous posts
My config:
Xiaomi, MIUI 12.5/A11, Magisk Canary 25205, Zygisk, DenyList (configured but not enforced), Shamiko and USNF (Display mod, not only for SafetyNet but also for the new Play Integrity), LSPosed + Hide My Apps
