Inside share-config-custom.xml, you need to use predefined elevator for disabling actions.You can use below evaluator for permanently disable the action.

evaluator.doclib.action.disableAction

Example : For disabling download actions

<config evaluator="string-compare" condition="DocLibActions">

<actions>
<!-- Download document -->
<action id="document-download" type="link" label="actions.document.download">
<param name="href">{downloadUrl}</param>
<param name="target">_blank</param>
<evaluator>evaluator.doclib.action.disableAction</evaluator>
</action>

</config>

oh  thanks ! I do it as you say, but it doesn't work

<!-- Download document -->
<action id="document-download" type="link" label="actions.document.download">
<param name="href">{downloadUrl}</param>
<param name="target">_blank</param>
<evaluator>evaluator.doclib.action.disableAction</evaluator>
</action>

Is it the wrong value of label？

Because of the screen shot not being in my language, I am not able to identify the action id, you need to figure on your own.Above code should be in proper place and it will only disable the download action.
