Burning i.MX6 Fuses with UUU

I know that U-Boot can write the fuses, but how is this done from UUU?  I have searched the UUU PDF file, and the word "fuse" does not occur in the document.

This suggests that it is possible (see #2):

imx6 Secure Boot Questions

Looking at the UUU document, Table 2, SDP should be used with i.MX6.  UUU documentation does not mention "+FB".  So what is the difference between FB and +FB?  Is +FB valid for the i.MX6?

From Burning_eFuses_on_i.MX8_and_i.MX8x_families:

SDPS: boot -f imx-boot-imx8qxpmek-sd.bin-flash
+FB: ucmd fuse prog -y 0 708 0xa295fc11
+FB: ucmd fuse prog -y 0 709 0x000017b4
FB: ucmd setenv fastboot_dev mmc
