you turn the touch pad as a mouse feature off. then just clicking it in is same as select button. the pointer will also go away when not selecting items while that feature is off. i believe it can be found in controller settings if i remember correctly but after beta phase 2 i immediately turned it off because essentially its not a good feature especially for any combat lol theres actually some pretty useful info about ps4 controls in the manual on the log in screen, not being sarcastic it helped a bit.
