You can implement the following workaround to disable the CEIP Data Collection Job.

1.) Launch an elevated SharePoint 2010 Management Shell

2.) Run the following command to find out the current status of CEIP at the Farm and Site level

Get-SPBrowserCustomerExperienceImprovementProgram -Farm <- This will return the status of the Browser CEIP at the farm level
(Get-SPFarm).CEIPEnabled <- This will return the status of the CEIP at the farm level
(Get-SPWebApplication).BrowserCEIPEnabled <- This will return the status of the CEIP at the site level

3.) If CEIP is enabled, run the following commands to disable CEIP at the Farm and Site level

Set-SPBrowserCustomerExperienceImprovementProgram -Farm -Enable:$FALSE
Set-SPBrowserCustomerExperienceImprovementProgram -WebApplication "SBS SharePoint" -Enable:$FALSE

4.) Next, open SharePoint 2010 Central Administration

5.) Click System Settings

Get-SPTimerJob job-ceip-datacollection | Disable-SPTimerJob
