3] Change Windows Defender Real-time Protection feature settings in Task Scheduler

5] Exclude Valorant game and anti-cheat folder from Windows Security or your antivirus
Windows Security protects your computer from potential threats. When Windows Security runs a scan on your system, it usually consumes more CPU. If you are experiencing a high CPU usage issue with Valant, it might be possible that Windows Defender or your antivirus software is running a scan for Valorant. To solve this issue, you can add the Valorant game and anti-cheat folder as an exclusion to Windows Security and to your third-party antivirus.
6] Troubleshoot in a Clean Boot state
The issue might be occurring due to conflicting third-party software. Troubleshoot your computer in a Clean Boot state to identify that software. Once you find the culprit software, consider uninstalling it.
How do I fix high CPU usage?
There are several causes of high CPU usage on a Windows OS, like corrupted system files, conflicting software, etc. To fix this problem, you can run an SFC scan, DISM scan, chkdsk scan, update your device drivers, etc. Running the Performance Troubleshooter can also help fix the problem.
Hope this helps.
