Sure, I recommend the Purism Librem 14 v1, which is the laptop I use. It has two hardware kill switches, supports up to 64 GB of DDR4 RAM @ 2666 MHz, and supports at least two Coreboot payloads, SeaBIOS and Heads. Unlike the thread linked above, I have no issues using Qubes.
Otherwise, if you want more options, see the list of community-recommended computers.
