How to hide certain column on drill down table?

I have a dimension like as follows

dimension: col1 {
type: string
hidden: yes
sql: ${TABLE}.col1 ;;
}

measure: loss_percent {
type: number
sql:
case
when ${loss} > 0 and ${total} > 0 then
ceiling((${loss} / ${total}) * 100)
else 0
end ;;
html:

{{ rendered_value }}
;; drill_fields: [drill_details*] }

set: drill_details {
fields: [event_time,rollup_a, rollup_b,
rollup_c, rollup_d, rollup_e,
col1]
}

in dashboard, I’m displaying loss_percent measure and if I click on drilldown col1 is getting displayed in drilldown as it’s passed in URL although it’s set to hidden:yes. Anyway to hide this col1 in drilldown? I need this data to generate a link in one of this drilldown dimension but not to be shown in drilldown table.

Is there a reason why you wouldn’t be able to just remove it from the drill details?
