Path in the GPO console
Computer Configuration\Administrative Templates\Google\Google Chrome\Extensions User Configuration\Administrative Templates\Google\Google Chrome\Extensions Description
Control if users can turn on Developer Mode on chrome://extensions. If the policy is not set, users can turn on developer mode on extension page unless DeveloperToolsAvailability policy is set to DeveloperToolsDisallowed (2). If the policy is set to Allow (0), users can turn on developer mode on extensions page. If the policy is set to Disallow (1), users can not turn on developer mode on extensions page. If this policy is set, DeveloperToolsAvailability can no longer control extensions developer mode. Note: This policy only applies to platforms that support extensions.

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
