Adding to what mxlky_moon said, you can use StarterGui:SetCore("ResetButtonCallback", false)
However if the coregui for “ResetButtonCallback” has not loaded it will throw an error. To combat this, add a pcall (protected call) and a simple loop to stop it. Like such:
repeat
local success = pcall(function()
starterGui:SetCore("ResetButtonCallback", false)
end)
task.wait(1)
until success
This is just an example, edit it to your hearts content.
