My question is:


According to the manual of iMX6, it mentioned that secure boot takes effect when DIR_BT_DIS and SEC_CONFIG in eFuse should be blown.


In the developing stage, can imx6 board use secure boot without eFuse blow?  (internal boot mode or serial download mode)


Is there any way (such as setting GPIO or registers) to get this effect?
