given it’s a touch screen / button combo unit, I would be doubtful you can remove the touch screen aspects of the config.

perhaps try making contact with the local Lowrance agent, however I don’t like your chances on removing that side part of the display, given the touch screen aspect is half the reason those particular units are so popular 

 Put your finger on the edge of the info bar where it meets the map and flick to the right as you would on an iPhone scrolling screens

 Hey Ryan, I have hds 7 gen 2&3 and you can definitely do what you are asking on both units. You can even set a time (ie 10,20,30 seconds) and it will automatically remove the menu bar. I just can't remember atm where the settings are. Fairly sure I found the settings via lowrance web site tutorials. 

 Hold menu button in for about 5 secs and then it will give you the whole screen

 As Jadeo said swipe right, in the unmarked part of the menu. The menu bar will disappear and menu will appear in the top right hand corner touch the menu and drag down to reveal the menu again 

 appreciate the help , ill give that a try this afternoon when i get home , there is always an answer on here!

You can also make the menu automatically disappear after 15 seconds by going to the home screen (where you can select Chart,Sonar,Structure etc), click Settings, System, Advanced, User Interface, Auto hide menu 

 appreciate the help! cheers 

 Swiping right works perfectly lads much appreciated I’ll now go into the menu and sort it to go off automatically cheers!
