Is it possible to make a batch of “Alter procedure” that are stored in a table?

Currently I have hundreds of sp that are in multiple servers, and that coexist with other sp that are in other servers with linked server. The origin of this is that when I do a restore of databases in development I need that these now point to their corresponding test version. Then I already created a script that searches in all the sp and saves in a table the sp with the modifications that I require. Now I can't manage to execute the sp to make the alterations of the SP.

-- Cursor variables
DECLARE @currentId INT;
DECLARE @currentSchema NVARCHAR(128);
DECLARE @currentName NVARCHAR(128);
DECLARE @currentScript NVARCHAR(MAX);
DECLARE @errorMessage NVARCHAR(MAX);
DECLARE @cleanScript NVARCHAR(MAX);

-- Start cursor
DECLARE procedure_cursor CURSOR FOR
SELECT Id, SchemaName, ProcedureName, AlterScript FROM AlterProcedures
ORDER BY Id;

OPEN procedure_cursor;
FETCH NEXT FROM procedure_cursor INTO @currentId, @currentSchema, @currentName, @currentScript;

WHILE @@FETCH_STATUS = 0
BEGIN
    BEGIN TRY
        EXEC(@currentScript);
        PRINT 'Updated ' + @currentSchema + '.' + @currentName + ' successfully.';
    END TRY
    BEGIN CATCH
        SET @errorMessage = 'Error in update:  ' + @currentSchema + '.' + @currentName + ': ' + ERROR_MESSAGE();
        PRINT @errorMessage;
        -- continue with the next even if there is wrong
    END CATCH
    
    FETCH NEXT FROM procedure_cursor INTO @currentId, @currentSchema, @currentName, @currentScript;
END

CLOSE procedure_cursor;
DEALLOCATE procedure_cursor;

--TRUNCATE TABLE AlterProcedures;
PRINT 'Process completed'

Result:

Error al actualizar dbo.SIIF_MotorMantenimientoFechaEjercida_sp: 'CREATE/ALTER PROCEDURE' debe ser la primera instrucción en un lote de consultas.

--> create/alter procedure' must be the first statement in a query batch
