Update 2026 : In /etc/brave/policies/managed/GroupPolicy.json
Paste this to fully remove AI, Rewards, VPN, Wallet and some other annoying things in the browser :
{
"BraveStatsPingEnabled": false,
"BraveP3AEnabled": false,
"MetricsReportingEnabled": false,
"BraveAIChatEnabled": false,
"BraveRewardsDisabled": true,

}
I also provide a automatic installation in my codeberg repository of the settings provided by @apparatus and @clammy thanks to them this will install the browser , remove ai , telemetry, etc…
