How to reduce the density/disconnecting of grass? (Apex Legends)

I play on a new map (Olympus kind) and on open areas (where there is grass) heavy drawdowns from 160 to 70-80 phps. If you look through the sight, it happens to 30. It is impossible to play, because I have 144 Hz and such drawdowns are very noticeable. How to fix, men? All put on a minimum, except textures and TAA.
