HomepageIsNewTabPage

Setting the policy to Enabled makes the New Tab page the user's homepage, ignoring any homepage URL location. Setting the policy to Disabled means that their homepage is never the New Tab page, unless the user's homepage URL is set to chrome://newtab. If you set the policy, users can't change their homepage type in Google Chrome. If not set, the user decides whether or not the New Tab page is their homepage. On Microsoft® Windows®, this policy is only available on instances that are joined to a Microsoft® Active Directory® domain, joined to Microsoft® Azure® Active Directory® or enrolled in Chrome Browser Cloud Management. On macOS, this policy is only available on instances that are managed via MDM, joined to a domain via MCX or enrolled in Chrome Browser Cloud Management.
