Stop x-axis ticks at start of month or year

[jakehoare]

With the following formatting:
sg_axis_x(sg, tick_interval = "day", tick_units = 10)

I get tick marks every 10 days and at the beginning of every month.
Similarly for tick_interval = "month" there is a tick at the start of every year as well as ticks at the required interval.

Is there any way to stop these extra tick appearing?
Thanks
