I assume you just want to set EKB as default and not "just" disabling the voice input which pops up when you disable the gboard.

We did it with this xml:

<wap-provisioningdoc>
    <characteristic type="UiMgr" version="4.3" >
        <parm name="InputMethodAction" value="1"/>
        <characteristic type="InputMethodDetails">
        <parm name="InputMethodOption" value="4"/>
        <parm name="InputMethodPackageName" value="com.symbol.mxmf.csp.enterprisekeyboard"/>
        <parm name="InputMethodClassName" value="com.android.inputmethod.latin.LatinIME"/>
        </characteristic>
    </characteristic>
    <characteristic type="EnterpriseKeyboard">
           <parm name="NavigationMode" value="1"/>
           <parm name="SelectPreferTab" value="2"/>
           <parm name="VoiceInputKey" value="2"/>
           <parm name="ShowScanTab" value="2"/>
    </characteristic>
</wap-provisioningdoc>

Be aware the second part are EKB settings you may need to align or leave out.
