Standard notebook design

There are some DIY type notebook in the market, like the Framework one, that user can replace individual h/w parts. I just wonder if there's a standard design of notebook of the same class that uses compatible h/w, such as display, wireless, power...etc., so that user can install different mother board on it. For example the Pinebook Pro, if the display in use is a common type, user can replace the m/b with a more powerful one, such as the new Pi 5. I don't know if there's any 'barebone' notebook available that user can customize with different m/b and add-ons of choice ?
