Yes, that's a pretty new feature, which requires v4.14.x-ti and an
updated bbb-cape-overlays package:

sudo apt update
sudo apt install --only-upgrade bb-cape-overlays

debian@beaglebone:~$ cd /opt/scripts/tools/
debian@beaglebone:/opt/scripts/tools$ git pull
debian@beaglebone:/opt/scripts/tools$ sudo ./update_kernel.sh --lts-4_14

sudo reboot
