Not in the UI directly. One option would be to use Workflows to create an enable & disable SSID workflow. Then you can create automation schedule rules to run at your specified time & days.
I just created a simple example in my Org. Created a workflow using the endpoint of "Meraki - Update Network Wireless SSID". Configured my network ID, SSID number, and "Input - Enabled" = false. True would equal an enable action on the SSID.
Then I created an automation rule type schedule. Gave it a name, schedule day & time, and applied to selected workflow of the workflow name I created in the previous step.
