How to remove trailing carriage returns

Question

I have this field that has chr(10) for each line at the end, however there are 2 CHR(10) at the end
I've tried replace but that didn't work also reading you can't use regexpr_replace with a negative value.
e.g.
This is line1 chr(10)
This is line 2 chr(10)
chr(10)
chr(10)
Any ideas please

If so:
RTRIM (str
      , CHR (10)

In regular expressions, a pattern can be anchored to the end of the string, like this
REGEXP_REPLACE ( str
            , CHR (10) || '$'
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only), and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
