Can we appear for interviews of two different roles at the same time in the same company?

I applied to a big MNC (one among faang) for the roles of SWE and SWE2. Two different HRs from that company sent me links to two different online assessment. The first role is of software engineer one in the city bangalore for some different team whereas the other role is of software engineer 2 in NCR location for some different team. I have cleared both the online assessments and my interviewes are scheduled for both roles, but the HRs are not aware that I am in for another role in that same company. Is this a violation of any kind? Should I inform the HR? I want to appear for both rou ds so that my probability of getting hired increases.
