Go to https://addon.bool.no and create an addon with this code:

local f = CreateFrame("frame")
f:SetScript("OnEvent", function()
    local shift = IsShiftKeyDown()
    PlayerFrame:EnableMouse(shift)
    TargetFrame:EnableMouse(shift)
    MinimapCluster:EnableMouse(shift)
    Minimap:EnableMouse(shift)
end)
f:RegisterEvent("MODIFIER_STATE_CHANGED")
