Can I hide ecommerce from my template to use it as a portfolio until I'm ready to sell? 

I'm just starting out with a line of pottery. Eventually I will be selling via my squarespace site, but until I'm ready I'd just like to use it as a place to showcase my work and start to work out the aesthetic of the design. 

Is it better to (and even possible) to start with an ecommerce template and hide the ecommerce page until I'm ready to sell

OR

Start with a portfolio template and switch to ecommerce? 
 

My fear is that I'll have to rebuild a lot of things if I switch templates and I'd really rather avoid that. 

Thanks for your help in advance!
