How to edit snowflake string?

Here are my default snowflake bridges in tbb:

snowflake 2B280B23E1107BB62ABFC40DDCC8824814F80A72 fingerprint=2B280B23E1107BB62ABFC40DDCC8824814F80A72 url=kkkkkkkkkgggg,,,,,,,, utls-imitate=hellorandomizedalpn

snowflake 8838024498816A039FCBBAB14E6F40A0843051FA fingerprint=8838024498816A039FCBBAB14E6F40A0843051FA url=kkkkkkkkgggg,,,,,,,, utls-imitate=hellorandomizedalpn

There are many articles on changing the front domain, but if I want to add more snowflake bridges manually, should I need to change 8838024498816A039FCBBAB14E6F40A0843051FA fingerprint=8838024498816A039FCBBAB14E6F40A0843051FA

to other value?

Not a Whonix specific question. Same as if using Tor / Tor Browser Bundle. See:

I am adding more than three snowflake bridges to Whonix

Ok, no problem.

Whonix doesn’t restrict you from doing so.
