No, vanguard cannot directly access your files on Linux.
Vanguard is a powerful tool in the game Valorant that operates at the lowest level (kernel ring 0). I have privacy worries because it starts up directly from the boot. For my setup, I use Windows only for gaming and Linux for other tasks. Does Vanguard have access to anything on the Linux partition?

Because it operates at the most basic kernel layer, it’s reasonable to think it has direct access to disk storage. This implies it can interact with other partitions on the same drive. If it contains logic for reading formats like ext4, it should logically support accessing files from your Linux partition. On the other hand, it might simply scan and forward all data for further processing.
It's very unlikely they'll reach your Linux file system unless you've mounted it via third-party tools under Windows. Even then, it depends on how it's mounted. The effort needed to set this up would probably not justify the advantages, given the many file systems available. If you're concerned, consider encrypting it, though I don't think you should stress too much about it.
It seems a built-in ext4 driver isn't available in anti-cheat solutions. The best options are restricting access to the second drive or partition using LUKS, or simply disconnecting it.
