Removing format from number field

[Gal Fatal]

Hi,

Using Jira Service Management on DC, Jira version 8.22.6

I created a number field to host the year in 4 digits.

After editing the field it presents the number with format, adding comma - 2,203

I would like to view the field and see 4 digits i.e 2023 , without any format, and keep it as number field without option to add letters.

I tried using automation but in this version it's poor and I do not have too much options.

Any idea for removing the format ?

Thank you
