<t>@4c74356b41's answer was correct, but now you can create as many build configurations using different yaml files and also with continuous integration without creating manual builds.<br/>
<br/>
On the new pipeline flow follow these steps:<br/>
<br/>
1. Choose where is your code:<br/>
<br/>
<br/>
<br/>
2. Select the repository of your code (the one which has the yml file):<br/>
<br/>
<br/>
<br/>
3. On the configure pipeline, choose Existing Azure Pipelines YAML file:<br/>
<br/>
<br/>
<br/>
4. Select the branch and the path where the yaml file is, then continue: Note: If it's not shown make sure your file has .yml extension<br/>
<br/>
<br/>
<br/>
5. Finally click RUN.<br/>
<br/>
Note: After creating the pipeline this way, it will have continuous integration activated, but if you still want to have manual building follow the next:<br/>
<br/>
Select your build and then Triggers:<br/>
<br/>
<br/>
<br/>
And then disable continuous integration:<br/>
<br/>
<br/>
<br/>
Or even easier, just add the line trigger: none to your yaml file.</t>
