You might want to rethink the laptop list. Telemetry and advertising is generally a function of the operating system and the installed software, not the hardware. Commercial operating systems like Windows, MacOS, and ChromeOS are the prime suspects here regardless of the hardware, so buying, for example, a System76 laptop and installing Windows on it will not give you any privacy advantages over a Windows-based Dell.
There may be some privacy advantages if the laptop uses CoreBoot instead of stock BIOS/UEFI.
