Yes, We can use the same parameter and apply calculation in filter and select all using this datasource. Please show same parameter in all dashboards then all dashboards will effect.

Click on the little drop down arrow on your filter and set it to Apply to Worksheets - then decide which you want it to apply to.
Quickfilters aren't contained only to the worksheet/dashboard they're on - you can set them to apply to as many worksheets as you want.
Thanks for the tips
Rookie mistake from my end
Some were still left on apply to this worksheet only
