What exact package are you installing? Office 365 Pro Plus or Office 2013?
As Biggles rightly mentions the options to remove access need to be done via Control Panel which will work for Office 2013 only.
Office 365 Pro Plus is different and will require you to Remove Office 365 completely and reinstall using the CTR and a custom XML file which will exclude the installation of Access.

Sorry but i’m not aware of any option to change the installation AFTER you install other than remove and install using the above method, I will no doubt be proved wrong soon enough though :)
