iCloud Private Relay or VPN

Since I always use Mullvad VPN on my iPhone, should I disable iCloud Private Relay?

There are also the ‘Limit IP Address Tracking’ option for individual networks and Safari’s ‘Hide IP Address from Trackers’ setting. Should I disable these as well?

I run Proton VPN 24/7 and leave private relay on as a “backup”. The VPN will override private relay so I don’t see any downside to just leaving it on.
