Short answer: yes — do it from web.config (or folder-level web.config) and, if needed, from IIS settings. That is more reliable than changing every page or relying on a BasePage/global.asax hack.

A simple, application-wide way to stop ASP.NET page output caching is to turn off the OutputCache at the app level (put this in the root web.config). This prevents ASP.NET's output-cache module from caching pages or honoring @OutputCache directives:

<configuration>
  <system.web>
    <caching>
      <outputCache enableOutputCache="false" enableFragmentCache="false" />
    </caching>
  </system.web>
</configuration>

See the OutputCache configuration/property documentation for details. (learn.microsoft.com)

Static files and IIS-level output caching are separate. To stop browsers caching static files in a particular folder, add a folder-level web.config with a clientCache setting; to turn off the IIS output cache entirely use the caching element:

<configuration>
  <system.webServer>
    <staticContent>
      <clientCache cacheControlMode="DisableCache" />
    </staticContent>
  </system.webServer>
</configuration>
<configuration>
  <system.webServer>
    <caching enabled="false" />
  </system.webServer>
</configuration>

These control client (browser) cache headers and IIS output-cache behavior respectively. (learn.microsoft.com)

Notes and troubleshooting: 's BasePage approach works but is less complete — it only affects pages that inherit the base class and runs inside ASP.NET; it won't change how IIS serves static files or how a proxy/CDN caches content. Global.asax BeginRequest header-setting also works for dynamic responses but is not a substitute for the two web.config/IIS controls above. After you apply changes, recycle the app pool (or touch web.config), then verify in the browser DevTools Network tab that responses show the Cache-Control/Expires/Pragma headers you expect. (learn.microsoft.com)

I am not sure if there is way of disable caching using web.config file as this setting is more browser oriented.

I understand you want to just disable caching eveywhere by changing at one place. You can create a parent page and put the above code in the same and all the pages inherit from the same.

Configure the OutputCacheSection. It is used to configure app-scope settings. Have a look at MSDN article - Cache Configuration in ASP.NET
