You certainly can:
1- check other similar questions related to your idea
2- ask experts how to plan your customer segmentation and validation
3-look for experts that can help you understand the data you have gathered via research and/or customer validation.

These are obvious suggestions but you want to leverage experience and expertise when it comes to validation. Do make sure though to have done your homework and enough research beforehand. You don't want to be ready for a pivot right after a call.

Good luck and contact if needed.
