I wouldn’t recommend pouring it on a lawn unless you’re handling very small amounts of near room temp grease or you know you have a lawn that has properties good for filtration. Even then I’d avoid it because dogs or animals might try to tear up the lawn.
If you have a fenced compost pile with proper cover material it shouldn’t be a problem as long as you have enough cover material (such as straw or wood chips) to absorb the grease.
Or just pour it on the lawn somewhere. Don’t keep using the same spot.
