How to highlight or bold a specific axis label?

Let’s say I have the following plot

import plotly.express as px
data_canada = px.data.gapminder().query("country == 'Canada'")
fig = px.bar(data_canada, x='year', y='pop')
fig.show()

I want to be able to bold, or highlight, or make ‘stand out’ a specific label, such as ‘1980’ in this case.
Is there a way to specify this?

Thanks!
