Can I customize the links for my website pages to not show the coachesconsole.com domain?

Yes, if you have a custom domain name of your own and point it to the Console IP in its settings. Instructions for this are in Website > Settings > section 'Website Prefix' > check the box in front of the option 'I want to use my own domain name for my Coaches Console website' > you will see the instruction on the right side of this option.
