stream – How to disable startup animation from centos with wayland-weston?

We bought a Qualcomm HPC QAM8775 with Gunyah as Hypervisor and Android and centos is running in parallel. But there is a startup animation is coming up before centos bootup which is a man coming and saying something. Need to disable this Animation. How can I disable? Centos display is configured using Wayland and weston. I’ve tried giving startup-animation=none in weston.ini. But still the man animation is there. Please provide a fruitful solution or tell me where I can find the source of that video
