In backend decrease height of text field whose max length is 256 or more

[apy]

In backend, is there a way to decrease the height of a text field, whose max length is 256 characters or more? OOTB, 256 is the limit for text fields to be shown as three "multi level text fields", meaning that

1. Text fields whose max length is set to 255 or less are shown in backend as one-row fields
2. Text fields whose max length is set to 256 or more are shown in backend as multi-row fields = three rows are shown

If I have a field of type 2 (256 characters or more), is there a way to still manipulate the style of the field so that it's shown in backend as one-row field?

Found a way to do this:

You need to CREATE a new column level True/False attribute 'is_multi_level', use it on the target Dictionary Entry and set its value as 'false'.

Solution found from here (note that there's a typo in the target post's screenshots):
