HDMI automatically switches when TV powers on.

I saw a similar post for this problem under QLED and The Frame, but the solution didn’t help for my tv.

I have my PS4 hooked up and when I turn on the tv it automatically turns it on and switches to the input. How can I stop this from happening?

I have the Samsung 43" Class TU690T Series LED 4K UHD Smart Tizen TV

If there's no setting in the PS4 to disable hdmi control you'll need a cec blocker.
