First, manually enter some text in each control's Tag property to
identify which group you wish that control to be part of, something
like "GroupA" or "GroupB".

Then use code to make just that one group of controls visible or not:

Dim ctl as Control
If [SomeControl] = Scenario1 Then
    For each ctl in Me.Controls
        if ctl.tag = "GroupA" then
            ctl.Visible = True
        ElseIf  ctl.Tag = "" Then
            ctl.Visible = True
        Else
            ctl.Visible = False
        End IF
    Next
Else
    For each ctl in Me.Controls
        if ctl.tag = "GroupB" then
            ctl.Visible = true
        ElseIf ctl.Tag = "" Then
            ctl.Visible = True
        Else
            ctl.Visible = False
        End IF
    Next
End If   

Only controls whose Tag property is GroupA or GroupB will be effected.
   

There are no control arrays in Access, but you can loop through the
controls collection and do things. Also there is a Tag property in every
control, so you could loop through all the controls and check the tag
property, if, for instance you wanted to exempt some of your controls:

Add this to a standard module:

Public Sub HideIt(frm As Form)
On Error Resume Next
Dim ctl As Control
   For Each ctl In frm.Controls
       With ctl
           If ctl.Tag = 1 Then
               ctl.Visible = False
           End If
       End With
   Next ctl
   Set ctl = Nothing
   Set frm = Nothing
End Sub

Then in your form, you can do:

If scenario1 Then
  HideIt
End If
