Eloquent Get Collection if it has at least one relation

I have a scenario where I have a model A that has 3 relations B, C, and D.
I’m trying to get collections in A where it has at least one relation
so I don’t want {id:1,B:[],C;[],D:[]} But I would accept {id:2,B:[{id:6}],C;[],D:[]}
I tried getting them by 3 has but that only gets it if it has all 3.
I also tried getting all then checking by if but I want a faster way.
