Nope. We have been carrying the same OPTEE flavour since AM62
in AM62A, AM62P and now in J722S

Yocto machine configurations:

AM62A: 
<https://git.ti.com/cgit/arago-project/meta-ti/tree/meta-ti-bsp/conf/machine/include/am62axx.inc#n18>
AM62P: 
<https://git.ti.com/cgit/arago-project/meta-ti/tree/meta-ti-bsp/conf/machine/include/am62pxx.inc#n15>
J722S:
