Disable JTAG on i.MX 7

Is there a way to disable JTAG on i.MX 7 permanently (e.g. using fuses?). The reference manual mentions a SJC Disable Fuse in Chapter "SJC Disable Fuse", as well as Secure JTAG control in chapter "Secure JTAG control". However, Chapter 5 "Fusemap" does not list any of this fuses (i.MX 6 has JTAG_SMODE and SJC_DISABLE listed, both are missing in the i.MX 7 reference manual)...


Best regards,
