No, as per the FCOM, my bolding:

“During takeoff and landing, new predictive windshear caution alerts are inhibited between 80kt and 400ft RA, and new warning alerts between 100kt and 50ft RA.

These inhibits do not remove existing predictive windshear alerts. If a warning/caution event occurs before those boundaries, it will remain on the display and the complete aural callout will be annunciated.”

Unless you were already receiving WS alerts prior to 80/100kts, you won’t receive an alert until after you are in the air.
