Connect to router over https

I just purchased an AC1750 to replace my dead WNDR 4700.  On the old router I could connect to it through a self-signed https connection, which was fine.  I didn't mind whitelisting the certificate as long as I could talk to the router over an encrypted connection.

But the AC1750 doesn't seem to support https.  Is this option gone?  I've worked through all the advanced settings so unless I've missed it, it doesn't seem to be available, which would be quite a shame.  I'm updated to firmware v1.0.1.12_1.0.11
