Hi Hardik,
As per the implementation of SfSchedule, there is no support for the customization of Inlineview height. The height value of an inlineView is a predefined value that is calculated using the height of two rows in month view. We suggest you use the agenda view mode in SfSchedule. In which we can customise the height of the agendaview with the help of the AgendaViewHeight property in MonthViewSettings. Please refer to the following UG link about how to set the height of the agenda view in SfSchedule.
Please let us know if you have any concern.
Regards,
