Ion Tab hidding back button



I have an ionic tab and would like to hide the back button for one my tab. is it possible?
How about the entire tab but not the rest of my page?
If you look at the code I added "hide-back-button=“true” when I want to disable it but obviously this doesn’t work.

I would like to do something like this.

<ion-tabs menu-close class="tabs-positive tabs-icon-top margin">

 <ion-tab title="Top Picks" icon="ion-m-food" href="#/app/foodlist">
  <ion-tab title="Locations" icon="ion-m-map" href="#/app/map-view">
  <ion-tab title="Vendors" icon="ion-ion-chef" href="#/app/explore"  hide-back-button="true">
