Issues with vanguard, account is now suspended.

Hello. I'll get straight to it. I installed valorant today on my new laptop (never downloaded before on this device) and I get a vanguard error saying it's blocking a system file from running. Fair enough. Look it up online, fix the error. Then error no. 2 where I can't sign into my account on riot client saying "Sorry, we're having trouble signing you in right now" I fixed that too after seeing online that I should change my DNS. Restart my PC again. Game does open. I join a swiftplay match and just as it's about to start the game exits itself and I get a message from vanguard. Which brings me to error no. 3, "This version of vanguard requires secure boot to be enabled" which is dumb. Why would it let me play the game and kick me out as soon as I start a match if I don't already meet all vanguard requirements? Anyway I can't turn secure boot off because I'm dualbooting linux and windows. Disabling secure boot just results in a boot failure where I can't load any operating system. After this I tried restarting and opening valo one more time only to be told my account has been suspended. What do I do?
