VC code says my "http://homeassistant.local:8123/" not secured

I’m accessing my HA instance though my laptop on the same home network.
Both HA and laptop are on the same home network.
And VC code says it’s not secured.
So as per most posts suggest, I need to make my HA url a https.
I have already configured and using Nabu Casa to access my HA through phone and while I’m outside of home.
So any idea how can I make my local HA url a https?
