Hello,
Is it possible to write the attached file to 0x1b000000 using MCU Programming Tool like FR-Cube
There is no restriction o n programming UTEST. It is just a normal flash which is set as OTP in NXP factory.
Follow the procedure described in reference manual for UTEST programming.
chapter 21.3 UTest NVM sector
MCU Programming Tool like FR-Cube without running code for hse enable?
Unfortunate I do not know your FR-Cube tool. Please consult such with your tool vendor.
Best regards,
Peter

Hello,
In these areas you can store you information.
make sure in case you are using UTEST DCF Start or Records, to store your data after 0xFFFF_FFFF_FFFF_FFFF space from your DCf data.
Also be aware that storing data after stop record will leave you will no possibility to add additional DCF records. So leave enough space.
Best regards,
Peter
