There is an in-wall version (VG-SOCR86U/ZA) for the 2019 The Frame TVs but 2020 model numbers are not shown in the list of compatible models. I called Samsung about 2 months ago to ask about this but was told at that time there was no in-wall version available for the 2020 models. It was not clear if they simply had not gotten around to adding the 2020 model number to the spec list or if in fact the 2019 is incompatible with the 2020 TVs.
