i.MX8X unused OTP words safe to use for customer purposes?

I am looking for a spot on the iMX8X OTP (or other on-chip non-volatile storage) to store roughly 64 8bit device identifier values.

After reviewing the Fusemap table (Table 7-1) in the IMX8X reference manual I am only seeing two words available for "Customer" use, along with a few bits here and there (Customer_OTP_word0 and Customer_OTP_word1, plus Customer_OTP_bit[7:0]).

After reading the section "7.2 Fusemap", I noticed that it mentions "The indexes from 272 to 543 are not being used", my question is if those indexes are not used should they be considered "reserved" or should I consider them as free to be used for my own purposes?
