No longer a flag-based switch
There used to be a way to disable it using
chrome://flags/ (Chrome Experimental Features) however that flag removed by Google.
I prefer not to install more applications (add-ins, extensions or anything)
You need to install software
Chrome does not natively provide the functionality you seek, ergo to achieve this functionality you will need to modify the code in some way.
If you are going down the path of bending Chrome to your will, you will need to install custom script such as an extension. Browser extensions are a very common method used to modify Chrome in order to add or remove functionality.
Chrome Webstore extensions could modify two behaviors to allow Chrome to behave as you prefer.
Behavior you need modified:
- Force Chrome to always use Google's
Chrome Extensions Search > hide doodles
- Redirect all
new tabs to a custom URL
Chrome Extensions Search > new tab redirect
Is it safe?

Extensions you can try
You can add and remove extensions, so if these don't meet your needs you might try others.
Bending Chrome to your will necessitates accepting the risk and overhead associated with selecting, installing, and testing extensions. The alternative is to use the Chrome browser as designed.
