Quicksilver Kernel Redmi Note: 8

I should start by confirming if there's an actual kernel called Quicksilver for the Redmi Note 8. Maybe it's a custom ROM's kernel or a third-party one. I can check some Android forums like XDA Developers. A quick search in my mind (since I can't actually browse the internet) tells me that XDA is a go-to place for custom kernels and Android modifications. If Quicksilver is a real kernel, there should be a thread there.
