Same exercise, different variation each time ?

Hi, I want to ask, is it ok to do different exercise each time i train, if it's same exercise, just different variation than my routine says ? Let's say I do barbell row, can I do next time inverted row or cable row ? Another example : can I do one training pull ups and next pulldowns ? One time incline barbell and second incline dumbbells? I'm asking because I train at home + gym a there is different equip I have at home, so if I keep exercise but do different variation each time, will strenght and hypertrophy suffer or it won't be that much difference than doin all the time one variation ? Thanks
