Hi Atif,
Thanks for your interest in Syncfusion products.
Currently there is no support for mentioned feature with “TimeInterval Customization” in Schedule Xamarin.Forms.
Please refer the UG link mentioned below for this support from our WinRT Schedule control, in which Time interval between the slots can be customized using the TimeInterval property. The default interval is One hour.

Could you please confirm us whether the feature used in the mentioned link is same as you expect?
