Replace has a Count and Start argument, setting Count to 1 will replace the first occurance:

Set fs = CreateObject("Scripting.FileSystemObject")
sf = "C:\folder_scripts\script.bash"

Set f = fs.OpenTextFile(sf, 1) ''1=for reading
s = f.ReadAll
s = Replace(s, "MODE=On", "MODE=Off",1,1)
f.Close
Set f = fs.OpenTextFile(sf, 2) ''2=ForWriting
f.Write s
f.Close

If the text could vary, for example, in the number of spaces between MODE and equals sign, you can read the text line by line (s=f.ReadLine) until you find the first line in which MODE occurs.
