Remove actions from the Talent Review Meeting

Remove greyed out actions from the TR Meeting

Hi,

I would like to ask around whether you have any better idea how to remove the not used actions under the Talent Review Meeting >> View Dashboard >> Actions

I would like to hide them from the managers' view. 
I checked under the HCM Design Studio, but I was not able to find how to do there. Is the only way to make these changes, using the page composer and hide them? 

Thank you,
Dora
