Education loan and choosing course

Hi everyone my name is Priyanka and I completed my bachelors in B.E (electronic instrumentation and engineering). I want to do masters in cyber security management and I’m confused to choose the university in UK, if my decision is wrong in choosing the course please anyone suggest which kind of courses are suitable for this, and also duration of the course and university and I wanted to ask that is there a way where i can get education loan of about 20-25 lakhs without any collateral and without co applicant as I don’t want to involve my family because they are not supporting. can anyone help me?
