Definitely
I think if you have a good vet, or trust in your vet, all will be fine. I know it is hard to 'stand up' to them sometimes because after all, they are the professional. And I have caved before (Jackson went under for a dental cleaning in April, and the tech told me he needed bordatella before the surgery, it's not something I had any desire to do again, but kinda just went 'okay' because he needed the surgery. I think had I spoken to the actual vet, it wouldn't have been a problem).
But anywho, he was due for rabies shot in May so we do follow the law on that (every 3 yrs) and they also asked me if I wanted to do DHP as well since it had been 3 years (since he was 1 year old), I politely said no thanks we'll be skipping those. And that was that.
At your first vet visit, I would just ask if you can just do DHPP and avoid lepto, corona or lyme (non-core vaccines). Rabies is given between 16 weeks or later depending on your county laws. Then you go back around 1 year of age for a booster of DHPP and rabies (preferably on different days). Then you won't have to worry about it for 3 years so you can have time to research and think about it.

PS- I got Jackson at 9 weeks old and we haven't had any problems.
