Approach for multi HttpPatch Api for One Entity

Hi 
I Have 3 patch API With 3 different Dto For modified One Entity :

which approach is better 

1- Create 3 services For Modified with 3 different DTOs (All Those Methods are the same)

2- Create 1 Service For Modified With One Dto Called "EditDto" And Map Those 3 DTOs To EditDto

3- Create 1 Service For Modified  With Entity As param And Map Those 3 DTOs To Entity
