Underrun protection for V70 I?

Hello, I recently drove dirt roads or dirty roads (construction site traffic). The car gets dirty, clear. But also the engine room gets dirty, I don’t have mud in there, but mud splashes everywhere. Is there a way to “do” the V70 I petrol without a big theater down, so that when you drive mud, flowers don’t grow in the engine room at some point? tia + mfg, Patrick
