is there any way to pass USERPRINCIPALNAME to direct query as a parameter

i use direct query in power service, connected to azure sql server.
i want to filter data by login user. i know, i can use RLS,
but i understand RLS just filters data in Power BI, not database site.

So i have get much data from DB site, before filtering it in Power BI by RLS.

that causes slow performance and 1 million record limit problem.
is there any way to pass USERPRINCIPALNAME to database as direct query parameter?

looking forward to your anwser.

thanks
