Can I claim heat pump and spray foam insulation that i paid for out of pocket during new build construction since it was not part of the original build plans?

I got a yes and no on this same question so asking for clarity. During construction, I paid out of pocket to improve the insulation and AC unit, it was not bundled in the loan. I paid cash. It was not part of the build plans, i paid for the efficiency improvements and would like to claim it as such. But can I?
