How to get default slicer value for second slicer?

Hi  AkhilReddyN ,

Here are the steps you can follow：

For the slicer that comes with Power BI, we can not get it. But we can get the three point in the "Visualizations", and we click the "Get more visual":

Then we find the "Preselected Slicer" and add the visual to our Power Bi Desktop.

First , we need to create a table with one column , and the value is True and False, like this:

Second, we can create a measure to define that we need default preselection values. If we need default preselection then we return True, otherwise we return False.

Measure =
var _select=SELECTEDVALUE('Table'[Column1])
var _step=SELECTCOLUMNS(FILTER(ALL('Table'),'Table'[Column1]=_select),"Column2",'Table'[Column2])
return
SWITCH(
    TRUE(),
    _select="cricket"&&MAX('Table'[Column2])="average",TRUE(),
        ISFILTERED('Table'[Column1])=TRUE()&&MAX('Table'[Column2]) in _step&&_select<>"cricket",TRUE(),         
    ISFILTERED('Table'[Column1]) =FALSE()&&MAX('Table'[Column2]) ="medium",TRUE()
)

Then we can put the 'Table'[Column2] in the Fields , [Measure] in the Pre Selection , 'Dirty Table'[Dirty Status] in the Dirty Status, like below screenshot:

Result:
