To update your content from Quarto to Static you will want to do the following:
You will need to log into the Connect Cloud website. Once you are logged in, you should be shown a list of content for your account. You will then want to locate your Quarto document in the list and go to the document’s settings by clicking the More Actions menu … and then clicking the Settings menu option.
Once you are at the document’s settings, you can click the Source navigation menu item and change the Framework from Quarto to Static. To save those changes you have to click the Republish button at the bottom of the screen.
I hope that helps,
Zak
