This controls whether Safe Browsing's standard protection mode is allowed to send partial hashes of URLs to Google through a proxy via Oblivious HTTP in order to determine whether they are safe to visit. The proxy allows browsers to upload partial hashes of URLs to Google without them being linked to the user's IP address. The policy also allows browsers to upload the partial hashes of URLs with higher frequency for better Safe Browsing protection quality. This policy will be ignored if Safe Browsing is disabled or set to enhanced protection mode. Setting the policy to Enabled or leaving it unset allows the higher-protection proxied lookups. Setting the policy to Disabled disallows the higher-protection proxied lookups. Partial hashes of URLs will be uploaded to Google directly with much lower frequency, which will degrade protection.
