Update number column with it's current value and new number

I need to convert this RAW sql query into a query in drizzle, but I can't find a way. Anyone done something similar?

UPDATE products
SET quantity = quantity + 15
WHERE id = <my-id>;

UPDATE products
SET quantity = quantity + 15
WHERE id = <my-id>;

UPDATE products
SET quantity = quantity + 15
WHERE id = <my-id>;

UPDATE products
SET quantity = quantity + 15
WHERE id = <my-id>;
