No, it’s not. That’s an impossible standard for the company to hold.
You buy the product under the assessment that you will void the warranty by doing XYZ, if you want that level of access you have made changes that could have damaged the battery and they don’t have the time to grill every wannabe tech douche to make sure they didn’t fuck up the device themselves.
They tell you what you can and can’t do with the product AND still receive support up front, case closed.
