How to make image with qt5-x11 support and It should be mount as read only at boot time?
Unfortunately, this may not simply be changed at boot time but needs a rootfs specially provisioned for it.
Can you give me some helpful links this is what I already try but It won’t work?
Is it true that with Qt 5 & x11 image can’t be make as read only. And suppose if I use console image with EGLFS buffer then It will able to run graphical qt5 Application?

What exactly about the link I gave you above which links to the very Yocto Project manual about the topic wasn’t helpful for you?

What exactly is it that you already tried and in which exact way is what exactly not working?

No, more or less anything may be configured/built as read only.
And suppose if I use console image with EGLFS buffer then It will able to run graphical qt5 Application?
No, you will need to build a specific Qt image with resp. graphical backend which has been discussed on this very forum more than once before.
BTW: What exact hardware (module and carrier board) and software versions of things are you talking about?
