Can confirm that this is affecting the Intel NUC8i5BEH on Ubuntu 20.04
with a Seagate Expansion Desktop 4TB USB 3 Enclosure attached.

To fix this, the NUC has an internal USB Dock controller which had to
have the quirk added in addition to the Seagate Drive.

/etc/modprobe.d/blacklist_uas.conf
options usb-storage quirks={USB3-CONTROLLER}:u,{SEAGATE-DRIVE}:u

Also disregard my previous bug addition for affecting Arch kernel. First
time working with Launchpad and pressed some buttons by accident :)
