Turn off "Keep Changes" for Display Settings: Windows 10.

i have a number of tvs on my system. one is in my bedroom and samsung has a "smart" scan that comes on when i change to my PC to my bedroom. this "scan" is anything but smart it ticks over for 20 seconds when the source is activated.... my problem is that "keep changes" from windows has a 15sec timer.
this means i cant click the option to keep the changes in time.

i have tryed to remove the smart scan from samsung - it wont go

if i could remove the timer completely from windows or just remove the pop up completly the HDMI sorce that i want to use would kick in no problem

please help !
