Passing Extra Arguments to Networkx Graphviz_Layout Not Working

I want to pass an extra argument to the graphviz_layout(), which I am doing, but it's not doing anything. I have also tried passing other arguments, but same problem.
It is correctly recognizing it, because if I change the argument I pass to something nonsensical I get an error.
I am referring to this documentation:
from networkx.drawing.nx_agraph import graphviz_layout
G = model.block_tree.tree
pos = graphviz_layout(G, prog='dot', root=0, args='-Grankdir="LR"')
plt.title(r"Blockchain with Selfish Mining ($\alpha$ = {})".format(alpha))
nx.draw_networkx_nodes(G, pos, node_color=color_vector, node_shape='s', node_size=300)
nx.draw_networkx_edges(G, pos, edgelist=G.edges(), arrows=True)
nx.draw_networkx_labels(G, pos, font_size=10, font_color="white")
plt.show()
Does anyone have an idea why it's not working?
This is the graph that I am producing. I would expect it to rotate, so that it is horizontal, but it's not...
Does anyone have an idea why? I'd be super grateful. Thanks in advance!
PS: There are some related posts, but none worked for me...

There's a conflict between the rankdir argument you're providing and the 'root' argument. If you remove the latter, it should respect your ordering.
Because I don't have your data, I made a simple example:
import matplotlib.pyplot as plt
from networkx.drawing.nx_agraph import graphviz_layout
import networkx as nx
G = nx.Graph()
G.add_nodes_from([0, 1])
G.add_edge(0, 1)
pos = graphviz_layout(G, prog='dot', root=0, args='-Grankdir="LR"')
nx.draw_networkx_nodes(G, pos, node_shape='s', node_size=300)
nx.draw_networkx_edges(G, pos, edgelist=G.edges(), arrows=True)
nx.draw_networkx_labels(G, pos, font_size=10, font_color="white")
plt.show()
This produces the following output:
But if I just remove the root=0 argument, I get:
