More importantly, did you have the chance to test OP-TEE?No, I didn't. I just enabled it and then built the kernel. I want to test it but when trying to insert OP-TEE module, I got this error:

Assuming you selected CONFIG_TEE=y and CONFIG_OPTEE=y, there's no module to load since they are built-in. You should see something I would recommend doing it this way rather than using =m and loading the modules separately, as that requires copying them into the root filesystem at the right location.
I have already done these and also set it =m.
I found that I should build OP-TEE first in the kernel [1]
But need to double-check with you, Is it correct? if yes, should I follow the steps related to FVP? and according to our discussion here [2], should I install the prerequisites [3] in the Morello-Linux container, and this step [4] will be in the workspace dir, then build it in the Morello-Linux container? if yes, should I use the `mount` command to do this or what? or everything will be in the Morello-Linux container? or are all these not needed and there is another way?
I don't have any experience with OP-TEE so I'm afraid I can't help with the specifics. It seems to me that those instructions are about building OP-TEE and you should probably do that on the host. As to running it on FVP, there is something about that here [1], but I'm not sure directly that would apply to Morello_FVP. You might need changes to the device tree, for instance.
Thanks, Kevin, I will try to figure it out, appreciate your help.
