Hi Anna Pullman-Rainbolt,
Thanks for reaching out to Microsoft Community and posting your inquiry.
We suggest using the Kiosk mode set up for Windows 10. Go to Settings > go to "Accounts -> Family & other users" page. On the right panel, click on the "Assigned access" option under "Set up a kiosk" section. > click on the "Get Started" button. > In the fly-out screen, name the Kiosk account > choose the app you want to use in the Kiosk mode (i.e Microsoft Edge). > In most cases you'll be ask two options, if just want a single web page to be shown in the browser then select "As a digital sign or interactive display" option. Click on the "Next" button to continue. > enter the URL of the homepage and set the interval when the Edge browser will reset to the homepage. Click on the "Next" button to continue. > click close and you're done.
For reference, you can use the Kiosk mode article.
