Incremental Refresh Issue Question

The Issue I have is that this BI file cannot seem to fold the data, as I cannot view the Native query and consequently I cannot define the incremental refresh type and period

- incremental refresh solutions is working on powerbi files that load data using Server IP connection to drive

My questions are:
> is there reason why the data source type (ie csv) or data source location (p drive) and data source import query (csv connection) would not work with data folding for incremental refresh
> if not, are there any fixes I need to do, to be able to finalize incremental refresh?

Here is the situation explained in detailed, on what I have done and where I have an issue

A> I have set the rules, on Desktop version (steps below)
#"Changed Type3" = Table.TransformColumnTypes(#"Duplicated Column",{{"Month - Copy", type datetime}}),
#"Filtered Rows" = Table.SelectRows(#"Changed Type3", each [#"Month - Copy"] >= #"Range Start" and [#"Month - Copy"] < RangeEnd),
Where RangeStart = #datetime(2021, 1, 1, 0, 0, 0) meta [IsParameterQuery=true, Type="DateTime", IsParameterQueryRequired=true]
Where RangeEnd = #datetime(2024, 4, 1, 0, 0, 0) meta [IsParameterQuery=true, Type="DateTime", IsParameterQueryRequired=true]

B> I would need next to define values for type of incremental refresh and period, on Spreadsheet view; as per print screen below, this is not enabled for me (issue2)
C> I have checked if BI can fold the data, but I see greyed out View Native Query (issue1)
