Server Logs Error - Could not find stored procedure 'sys.xp_dirtree' 'sys.xp_fileexist' and 'sys.xp_regread' on Azure sql server

My DNN v9.8 site is running on Azure server and getting server logs related to stored procedure 'sys.xp_dirtree' 'sys.xp_fileexist' and 'sys.xp_regread'
I found the stored procedures **xp_dirtree**, **xp_fileexist**, and **xp_regread** will not work because Azure SQL does not support these extended stored procedures for security reasons.
Please suggest if any direct solution or patch for this DNN version or if this issue is fixed in any of the latest DNN versions.
Thanks,
Mohd Shamim.
