Fuses for a really secure boot

Hello,

 

I have a i.MX6 Quad Core device and I installed a complete chain of trust secure boot solution in the eMMC. The bootloader is in SPI flash.
The device is closed and the SRK is burned in.
Which fuses I need to set additionally that's not possible to access the system without permission ?

I think about JTAG and some other fuses that I don't know at the moment...

 

Thanks
