Sorry for not being it clear, I indeed defined UBOOT_CONFIG = "nand"
in the local.conf. Should I define it as UBOOT_CONFIG += "nand" or
should I move it to a u-boot bbappend?

The mx6ull_14x14_evk_nand_config,ubifs was from a tip found and copied
from Internet, but the original definition is from included
meta-freescale/conf/machine/imx6ullevk.conf:

UBOOT_CONFIG ??= "sd"
UBOOT_CONFIG[sd] = "mx6ull_14x14_evk_config,sdcard"
UBOOT_CONFIG[mfgtool] = "mx6ull_14x14_evk_config"

I tried to use UBOOT_CONFIG[nand] = "mx6ull_14x14_evk_config,ubifs", no avail.

Yes, all enabled in my kernel 4.19.75:

CONFIG_MTD_UBI=y
CONFIG_MTD_UBI_WL_THRESHOLD=4096
CONFIG_MTD_UBI_BEB_LIMIT=20
CONFIG_MTD_UBI_FASTMAP=y
# CONFIG_MTD_UBI_GLUEBI is not set
CONFIG_MTD_UBI_BLOCK=y
CONFIG_DTC=y
CONFIG_OF=y

Yes, I am using the thud, the u-boot-imx_2017.03.bb is the same, here
is the link:

Thank you very much.

Kind regards,
