Is it possible to force a line on a form to read only by row/column vs by cell using Groovy?

Summary: I would like to have a groovy business rule set security on an entire column or row to read only vs having to do it by cell.

Content (please ensure you mask any confidential information): We have some very large forms and it takes longer to do the "setForceReadOnly" operation on each cell then I would anticipate it would to do an entire row or column. I am building a row to dynamically set entire rows or columns to read only but the setForceReadOnly is only working at the cell level. Is there a command available to do this by row or column so I can just look up the header and set multiple cells to read only at once?
