IMX6ULL.pdf states on page 314 (Device Configuration Data, Write data command):

If any of the target addresses do not lie within the allowed
region, none of the values are written. The list of allowable
blocks and target addresses for the chip are provided below.

Page 322 describes the SDP protocol. My expectation is, that the "address white list" for the DCD commands must also apply for the SDP commands. But I didn't find this on the documentation.

Q: Is it save to leave the SDP protocol enabled on a secure device (assuming a HAB version where ERR01087 has been fixed)?
