Need a help with First-Person Shooters + MXAO + SSR

I'm trying to use MXAO and SSR in first-person shooters. I tried to find the depth buffer in draw calls, but only the world displayed, and I couldn't find weapons. Possibly a weapon model using separated layers. So when I turn on MXAO or SSR, the MXAO and SSR effect display ABOVE the weapons. Does anyone know how to fix this problem? I already searched on Google, but none of them worked.

Here, I took screenshots. The map and a first-person weapon model are separated into two different depth buffers.

Also, I tried to disable effects using REST add-on, but this game doesn't show any shaders.

Anyone help please?
