There are measures that can be taken both through Chrome and the OS itself for parental control.
It is possible to apply parental controls to administrator users, as well as standard users. This allows you to (for example) hide violent games from the app center, or prevent yourself from running certain installed apps (similar to “digital wellbeing” features on other platforms). If your administrator user has a password set, the password is required to change these settings.
To access the parental control settings from the OS please access Settings then click on Details and select Users.
