r - Convert nvarchar of a column with dbplyr?

Question

Is it possible to replicate the following query in dbplyr:

SELECT convert(nvarchar(4000), column_name) [column_name]
FROM table_name

The 'convert(nvarchar(4000)' bit is what I'm interested in here. I'd guess that this would be outside the scope of dbplyr, but it would be great to know for sure. I'm using SQL Server.

Thanks!
